In an era where digital agility defines business success, enterprises can no longer afford to wait weeks—or months—for IT teams to build internal tools, automate workflows, or support evolving business needs. Today’s IT Service Management (ITSM) demands speed, flexibility, and collaboration across departments. But there's a problem: most IT teams are stretched thin. Between incident resolution, system upgrades, compliance audits, and managing change requests, traditional development backlogs are longer than ever. That’s where citizen developers and low-code/no-code (LCNC) platforms come in. In this blog, we explore how LCNC platforms are empowering business users to contribute directly to ITSM processes—reducing dependency on developers, accelerating innovation, and transforming how internal services are built and delivered. 💡 What Are Citizen Developers? Why this matters in ITSM: ITSM spans every department—from HR ticketing to facilities requests, procurement approvals, and onboarding processes. Allowing business users to build and customize these flows themselves (within governance limits) reduces turnaround times dramatically and improves cross-functional alignment. 🚀 The Rise of Low-Code/No-Code in ITSM ServiceNow App Engine In ITSM, these platforms are being used to: Automate onboarding/offboarding workflows The LCNC Way (Built on ServiceNow App Engine): HR built a custom onboarding form with drag-and-drop fields ✅ Onboarding time reduced by 70% Area Recommendation 📊 Business Impact of LCNC + Citizen Dev in ITSM Our LCNC practice helps: Identify high-impact use cases By embracing LCNC and empowering citizen developers, organizations can respond faster, deliver better, and scale smarter. ✅ Call to Action 📞 Book a strategy session with our LCNC + ITSM experts at MJB Technologies.

Have you ever wanted to SSH into your Android phone like it's a real Linux server? With Termux, Ubuntu, and Tailscale, you can do exactly that — without root! This guide walks you through setting up a fully functional Ubuntu environment inside Termux, exposing it via Tailscale, and making it the default shell on your phone. By the end, you'll be able to SSH into your phone from any device in your tailnet. 🧰 Prerequisites Android phone Tailscale installed and connected on both your phone and your PC Termux installed via F-Droid (not from Play Store — it’s deprecated!) Some Linux experience ⚠️ If You See This Error… You likely installed Termux from the Play Store, which is broken on modern Android. ✅ Step 1: Install Ubuntu (or any other distro) in Termux Using proot-distro pkg update && pkg upgrade pkg install proot-distro proot-distro list proot-distro install ubuntu To enter Ubuntu: proot-distro login ubuntu ✅ Step 2: Make Ubuntu the Default Shell in Termux Edit the startup script: nano ~/.bash_profile Add this to the end of the file: if [ -z "$PROOT_DISTRO_NAME" ]; then proot-distro login ubuntu-22.04 fi This prevents recursive launches if you’re already inside Ubuntu. Reopen Termux Now you'll land directly inside Ubuntu every time you open Termux. 🎉 ✅ Step 3: Set Up SSH Server Inside Ubuntu Launch Ubuntu: proot-distro login ubuntu Then run: apt update && apt install openssh-server passwd # Set root password service ssh start Now your SSH server is live on Ubuntu inside Termux. ✅ Step 4: SSH Into Your Phone via Tailscale From your PC: If you want to ssh into Ubuntu inside termux ssh root@ip -p 8022 or you can ssh into termux's shell by first: Inside termux whoami # it should be something like u0_a124 Then from your pc or other host device: ssh u0_a124@ip -p 8022 You can change the port in the sshd_config, or use the default 8022 if inside Termux.  ( 4 min )

React is a framework in Javascript, and on the most crucial aspects it has is State Management, Server-side rendering(SSR) and Hook Pitfalls. State Management Let's start from the basics, what is State? State can be defined as an object that houses data which changes over time in an application. In other words, state is a dynamic data storage that provides a mechanism for components to manage, keep track of changing data, and trigger re-rendering when it is updated. State management is like the brain of your app. It remembers everything the app needs to know at any moment — such as what you've typed in a form, whether you're signed in, or what screen you're looking at. When something changes (like you click a button), state management updates that memory and tells the app to show the ri…  ( 6 min )

Learn how the Factory Method pattern helps create flexible, decoupled object instantiation in your .NET apps. The Factory Method pattern is a creational design pattern that defines an interface (or abstract method) for creating an object, but lets subclasses decide which class to instantiate. It decouples client code from object creation logic—perfect when your system needs to support multiple product types or dynamic creation at runtime. Use Factory Method when: You want to delegate object creation to subclasses. There are multiple product types selected by configuration or runtime data. You want to follow SOLID principles like DIP and OCP. Common scenarios include plug-in architectures, UI element generation (buttons, dialogs), and different notification types. The pattern typically invo…  ( 4 min )

artificial intelligence, storytelling is undergoing a quiet revolution. Traditionally, stories have been the product of human creativity—an intimate process of weaving imagination, emotion, and experience into narrative form. But what happens when machines take the reins of creativity? Enter the Perchance story experiment: a fascinating intersection of randomness, code, and AI that is redefining what it means to create. At its core, a Perchance story is a narrative generated through procedural text—meaning it is created using rules, templates, and often random variables programmed into a generator. These stories are typically powered by platforms like Perchance.org, where creators can design interactive generators that use logic and chance to produce endless variations of text.

Digital marketing has always focused on getting more clicks. But clicks don’t pay the bills—conversions do. Now, with AI shaping search results, what matters most is what users do after they land on your page. Getting found is only half the job. The other half is turning that visit into action. Clicks don’t mean success A user clicking on your link doesn’t mean they’re interested. They might bounce in seconds. Maybe the page didn’t load fast enough. Maybe they didn’t find what they expected. In digital marketing, clicks are easy to track. But they can be misleading. A page with lots of clicks and no conversions wastes your time and budget.

I’ve seen too many promising teams fall apart not because of code quality, but because of silent, unresolved conflict. In our engineering community, arguments are part of daily life. If you’ve ever seen two developers argue over a variable name, you know what I mean. But the real danger isn’t the argument — it’s when everyone stays silent and lets the resentment grow. In engineering, we obsess over technical debt and outdated services, but rarely talk about what sinks teams: unresolved, mostly unspoken conflict. It’s not always the dramatic shouting matches; more often, it’s the slow build-up of unspoken tension and half-solved disagreements. Why does this matter? Meetings become rituals, and only safe topics are allowed. The hard questions? Ignored for "next time." People stop pushing …  ( 8 min )

Last week, I ran into one of those annoying little tech moments. I was away from my usual setup, working on a basic office desktop with no Microsoft Office installed. Someone sent me an Excel (.xlsx) file over Slack, and all I needed was to quickly check a few numbers—nothing more. Normally, I’d upload it to Google Sheets, but the network had strange restrictions that blocked uploads. Logging into accounts on a shared machine didn’t feel right, and installing new software wasn’t an option. After clicking through a few sketchy “free viewers,” I finally found a tool that just worked. You upload the file (or paste a URL), and it renders your spreadsheet directly in the browser—no ads, no sign-ins, no remote uploads. Everything runs locally, and your document never leaves your device. Fast, clean, and effortless. Even better, it comes with some really thoughtful features: ✅ View Excel spreadsheets without needing Microsoft Excel or Office 365 ✅ Navigate between multiple sheets with ease ✅ No registration or login required ✅ Files are processed privately, entirely within your browser ✅ Simple drag-and-drop upload ✅ Fullscreen viewing mode for better readability If you ever find yourself in the same situation, you can try it here. Not flashy, but it saved me time and frustration. If you know other minimalist tools like this that just work, drop them in the comments—I’d love to check them out.  ( 3 min )

MBTJ Imagine it’s a Monday morning. The sun peeks through your window blinds, and your to-do list glares back at you—a tangled jumble of tickets, meetings, and half-finished side projects. You sip your coffee and wonder: “How will I actually get deep, uninterrupted work done this week?” That was me (Hi, I am HyungWoo, you can call me Eric), a software engineer buried under an avalanche of context switches. I loved Linear for tracking issues, but it lived in its own world. Google Calendar managed my meetings, but had no idea about my development tasks. Worse, every time I estimated a card in Linear, reality laughed in my face when I discovered I’d actually spent twice the time. Weekends blurred into evenings of “catch-up” work, and burnout loomed on the horizon. I always blocked out chunks …  ( 4 min )

Or: How I Discovered Why Nginx Doesn't Use 10,000 Threads and Nearly Had a Mental Breakdown When we left off in Part 1, I had built what I thought was a pretty solid multi-threaded TCP server. It handled multiple connections, had proper cleanup, and even graceful shutdown. I was feeling pretty good about myself until I ran some basic load tests and watched my beautiful creation crumble like a house of cards in a hurricane. The problem wasn't bugs in my code - it was the fundamental architecture. My thread-per-connection model hit a wall around 200 concurrent connections, and it wasn't even close to graceful degradation. The server didn't slow down - it just started rejecting connections entirely. Memory usage was through the roof, and CPU was spending more time switching between threads th…  ( 13 min )

If you're building backend services in Node.js, you’ve probably faced bugs that feel like they appear out of nowhere—silent failures, unexpected crashes, or just inconsistent behavior that doesn't show up in local testing. We certainly did. Our team had been working on a relatively complex Node.js backend powering APIs for a client-facing web dashboard. But no matter how many unit tests we wrote or code reviews we did, strange issues kept creeping into production. Then, we made a small but powerful change: we introduced one middleware function. It didn’t refactor our logic or change any major architecture. It simply caught what was already there—errors hiding in plain sight. To our surprise, that one middleware fixed over 90% of our runtime bugs. Let’s break it all down—what the middleware…  ( 7 min )

UX design plays a vital role in the success of any digital product, helping to drive higher user adoption rates and ensuring sustainable growth over time.  This role becomes even more critical in the context of SaaS products, where the complexity of features and workflows often presents a steep learning curve for many users.

The terms stateful and stateless describe whether a system or component maintains context (state) between interactions (such as API calls, sessions, or processes). Stateful A stateful system remembers previous interactions. It maintains data (state) across requests or sessions. Stores session info between requests. Requires memory/persistence layer (e.g., session store, database, in-memory cache). Ideal for long-lived workflows or real-time interactions (e.g., chat, streaming, games). Stateful API: A login session stored on the server (e.g., express-session with Redis). WebSocket connection: Keeps user state alive during a conversation. Database connection pools: Keep the connection state between requests. Harder to scale (e.g., sticky sessions or external session store needed). Higher …  ( 5 min )

Why Consensus Algorithms Matter More Than You Think (And How to Pick the Right One) I've been building distributed systems at scale for several years now, from real-time recommendation engines to high-reliability emergency platforms. If there's one thing that kept me up at night in my early days, it was consensus algorithms. Not because they're impossibly complex, but because choosing the wrong one can absolutely wreck your system's performance and reliability. Let me save you some sleepless nights by breaking down what I wish someone had told me when I was designing systems that needed to handle 50K+ events per second with zero tolerance for inconsistency. Picture this: you have multiple servers that need to agree on something. Maybe it's which server should be the leader, or what order…  ( 5 min )

Scaling isn't about having the perfect architecture from day one. It's about building systems that can evolve, monitoring them obsessively, and learning from your inevitable failures. Over the past few years, I've had the privilege of scaling systems at two major tech companies—from transforming an advertiser intelligence platform to building a notification system that processes 50K+ events per second. The journey from "this batch job runs overnight" to "we need real-time recommendations with 80%+ confidence" taught me some expensive lessons about scaling distributed systems. Here's what I wish I'd known before our first real-time migration broke everything (twice). The Disaster: At my current company, we had a beautiful batch processing system for our advertiser intelligence platform. It…  ( 9 min )

Hey there, today we’re diving into an exciting project: building a Payment Gateway API using Django and PayPal!

A leap second is a one-second adjustment made to Coordinated Universal Time (UTC), the global standard for timekeeping, to reconcile the discrepancy between precise timekeeping (based on atomic clocks) and the Earth's slightly irregular rotation. While this adjustment is intended to keep our clocks aligned with solar time, it has historically caused significant technical challenges, particularly in computer systems. One notable instance of such disruption occurred in 2005, when a leap second led to a massive glitch in the Linux operating system. Below, we explore what a leap second is, why it exists, and the specific reasons behind the Linux glitch in 2005. A leap second is an additional second inserted into (or, in rare cases, removed from) the UTC time scale to account for the gradual sl…  ( 8 min )

AI was supposed to make development easier. What we’re left with is half-understood code, test coverage duct-taped together, and developers trusting output they didn’t write, don’t own, and can’t fully explain. So now we’re here: Here’s how we got here—and what nobody’s saying out loud. 🧠 Prompt Engineering Isn’t Engineering Prompt engineering sounds smart—until you realize it’s just creative Googling with better grammar. We wrote about why the term “engineering” doesn’t belong here. Because if your process breaks when phrasing changes, it’s not engineering. It’s trial-and-error with a marketing spin. 🔀 AI vs Traditional Coding Isn’t the Right Debate People love debating whether AI will replace traditional coders. Traditional coding builds muscle memory. AI coding builds dependency. 🧨 We’re Creating Technical Debt Faster Than Ever The more you rely on AI, the less you review what it does. This isn’t a rant—it’s a warning. By the time you’re fixing it, the damage is already deployed. 🧟‍♂️ And Now It’s Writing SEO Content Too... It’s not just code. AI is now pumping out articles that say nothing—but rank anyway. And just like bad code, bad content piles up until the signal gets buried. AI’s not the problem. We’ll keep debugging, rewriting, and firefighting until we treat AI as a tool, not a shortcut. You just swapped one problem for another. 🔍 This post was reframed from EngineeredAI.net — ☕️ Buy Me a Coffee if this saved you from another AI-generated mess. I run this blog solo. No sponsors.

在 Java 中，InvocationHandler 和 Proxy 是实现 动态代理 的核心组件，属于 Java 的反射机制（java.lang.reflect 包）。动态代理允许在运行时动态创建代理类，用于拦截和增强目标对象的方法调用。以下是对 InvocationHandler 和 Proxy 的解释，以及它们如何实现动态代理的详细说明。 什么是 InvocationHandler 和 Proxy？ InvocationHandler InvocationHandler 是一个接口，定义在 java.lang.reflect 包中。 作用：它是动态代理的核心逻辑，负责处理代理对象的方法调用。 接口定义： public interface InvocationHandler { Object invoke(Object proxy, Method method, Object[] args) throws Throwable; } invoke 方法： proxy：代理对象本身（通常不直接使用）。 method：被调用的目标方法（通过反射获取）。 args：方法调用的参数。 返回值：方法执行的结果。 实现 InvocationHandler 接口的类可以自定义方法调用的行为，比如在方法执行前后添加逻辑（如日志、事务、权限检查等）。 Proxy Proxy 是一个类，也在 java.lang.reflect 包中。 作用：用于在运行时动态生成代理类，代理类会实现指定的接口，并将方法调用委托给 InvocationHandler。 核心方法： public static Object newProxyInstance(ClassLoader loader, Class[] inter…  ( 4 min )

Security is a crucial aspect of web development, and while much of the focus is often on backend protections, HTML itself offers several ways to enhance security. Here are five HTML tips to help you build a more secure website. 1. Use `rel="noopener noreferrer" for External Links When using target="_blank" on anchor () tags, always include rel="noopener noreferrer" to prevent security risks like reverse tabnapping. html This prevents the new page from accessing the window.opener property of your site, reducing the risk of malicious attacks. 2. Sanitize User Input with sandbox in If your site embeds third-party content using , always use the sandbox attribute to restrict what the embedded content can do. `html ` This prevents actions like form submissions, pop-ups, and script execution unless explicitly allowed. 3. Enable HTTPS with Use the Content-Security-Policy (CSP) meta tag to enforce secure connections and prevent mixed content issues. html This automatically upgrades HTTP requests to HTTPS, reducing man-in-the-middle attack risks. 4. Prevent Form Hijacking with SameSite Cookies While primarily a backend setting, you can help secure forms by ensuring cookies are marked as SameSite (handled via server headers). However, you can reinforce security by using: `html ` Avoid GET for sensitive data, as it exposes parameters in the URL. 5. Disable Autofill on Sensitive Fields For fields that should not be stored in the browser (e.g., one-time passwords, security codes), disable autocomplete: html This prevents browsers from storing sensitive information that could be exploited. Final Thoughts While HTML alone won’t make your site completely secure, these practices add an extra layer of protection. Combine them with proper backend security (like input validation, CSRF tokens, and HTTPS) for a robust defense.  ( 3 min )

The 3 types of developers In my experience, there are 3 types of people drawn to programming; “The Tourist”, “The Puzzle Master”, and “The Builder”. The tourist is someone that has no real interest in programming itself, or what you can do with it. They are more interested in how it can allow them to change their lifestyle. They may care about the higher pay, allowing for a better living space, or to get away from the work culture they are used to in a different industry, or the aspect of being able to work remotely. You’ll often hear people from this group say something like “I just want to be able to travel and work from anywhere”. Hence the name “tourist”. Though this group often doesn’t last long, either leaving the industry, or changing position to management or something else that …  ( 6 min )

I learn git at 2020 but 5years later I can still not use it well “变基”（rebase）是 Git 里的一个操作，主要用来整理提交历史，让代码的历史更清晰、更线性。 假设你有一个远程分支 origin/master，你从它拉了一份代码到本地开发分支 feature，你在本地做了很多提交。这时，远程 master 又有了新的提交。如果你想把远程 master 的更新合并到你本地分支上，有两种常用方式： 合并（merge）：会产生一个合并提交，把两个分支的修改合并在一起，历史会出现分叉和合并的轨迹。 变基（rebase）：把你本地的提交“搬到”远程 master 的最新提交之后，好像你是基于最新的远程代码做的开发。这样历史看起来就像一条直线，没有分叉。 master: A --- B --- C \ feature: D --- E --- F 远程 master 现在有提交 A-B-C，你本地 feature 分支在 B 的基础上做了 D-E-F 三个提交。 执行变基（git rebase master）后： master: A --- B --- C \ feature(rebased): D' --- E' --- F' 你的提交 D, E, F 被“重新应用”在 C 之后，形成新的提交 D', E', F'。 优点： 提交历史整洁、线性，更易读。 避免多余的合并提交（merge commit）。 缺点： 变基会重写提交历史（生成新的提交哈希）。 已经推送到远程的分支如果执行变基后再推送，必须用 --force，会覆盖远程历史，可能影响其他协作人员。 在本地分支更新远程分…  ( 3 min )

Imagine a party brimming with people. You, as an observer, notice certain groups forming naturally: a cluster of people engrossed in a lively conversation, another huddled around a board game, and a quieter group enjoying the music. You haven't assigned anyone to a group; the groups emerged organically based on shared behaviours and interests. This natural grouping is the essence of unsupervised learning, specifically clustering. Unsupervised learning is a powerful branch of machine learning where algorithms learn from unlabeled data—data without predefined categories or targets. Unlike supervised learning, which uses labeled data to make predictions (e.g., classifying emails as spam or not spam), unsupervised learning aims to uncover hidden patterns, structures, and relationships within t…  ( 6 min )

Hey, algorithm adventurers! 🔍✨ Today we’re diving into a tricky substring frequency problem from LeetCode — 3445: Maximum Difference Between Even and Odd Frequency II. This one mixes frequency parity, substring windows, and greedy insight. Let’s break it down and crack it open. 💡 Given a string s consisting of digits '0' to '4', and an integer k, your task is to find the maximum difference freq[a] - freq[b] in a substring of s of size at least k, where: Character a has an odd frequency. Character b has an even frequency. You can pick any substring and any two characters (a ≠ b). If no such substring exists, return -1. The challenge here is tracking character frequencies in valid substrings and comparing their parity — without scanning every substring (which is too slow). Our optimized id…  ( 6 min )

How Linux Gave Me Faster Internet (Without Even Trying) The Setup I dual boot: Windows 11 on one side, Linux Mint on the other. Same machine. Same Wi-Fi. Same network conditions. But here's the twist — I’m not running stock Windows. Before anyone says “bloatware did it,” I already stripped it clean. I went all in: Custom scripts to remove bloat and telemetry Disabled background services, ad systems, and syncing Registry cleaned up Defender? Gone. Xbox/GameBar? Gone. OneDrive? Not a chance. I even split my network into separate 2.4GHz and 5GHz bands, then forced the laptop to stick to 5GHz so it would stop jumping around and tanking speeds. And after all that work? Best-case download speed: 5–20 Mbps, fluctuating, and occasionally disconnecting. Installed Mint. No tweaking. No tuning. No custom anything. Boom. 35 Mbps, stable. No bouncing, no hiccups, no weird background processes eating bandwidth. It just worked. I could get technical about network stacks, background tasks, and invisible Windows daemons doing who-knows-what — but the short version is: Linux doesn’t assume ownership of your connection. It asks nothing, and it gets out of the way. I spent hours customizing Windows to behave itself. Linux behaved by default. If your connection is flaky and you've tried everything... maybe the problem isn't your router, or your ISP, or your drivers. Maybe the OS just talks too much.  ( 3 min )

Naviguer dans l'écosystème Google Cloud Platform peut parfois s'apparenter à l'exploration d'une métropole tentaculaire. Des centaines de services, chacun doté de sa propre puissance, offrent des possibilités quasi infinies. Mais comme dans toute grande ville, des réseaux souterrains et invisibles connectent chaque quartier. Dans GCP, ces réseaux sont les dépendances entre les services d'API, des liens cruciaux mais étonnamment absents des cartes officielles. Quand on travaille avec Google Cloud Platform (GCP), on finit toujours par passer par la case gcloud services enable. Que ce soit pour Cloud Functions, BigQuery, ou l’incontournable IAM, chaque service repose sur un ensemble parfois obscur d’APIs qu’il faut activer dans un ordre souvent flou.

When you build or buy a new PC, it often feels like you’re handing over a hefty chunk of your budget around 10%, just for the Windows license. But does it really need to cost so much? And what are your options if you want to avoid spending a fortune on an operating system that sometimes feels more like a surveillance tool with ads than a clean, straightforward platform? Let’s dive into the different ways to get Windows, from official to unofficial, and even free alternatives, so you can decide what’s best for your wallet and your privacy. Let’s start with the most official route: purchasing Windows straight from microsoft.com. You might expect this to be the easiest and most straightforward option, but surprisingly, even Microsoft seems reluctant to make it simple for you to pay them. The …  ( 8 min )

I’ve finally put together a minimal, terminal-inspired website for myself at m-mdy-m.github.io (code lives here ► GitHub). It’s built with GitHub Pages so it’s free, dead simple to deploy, and completely CLI-themed—think of it as a little shell where you can ls my posts, projects, and articles. So far, I’ve published a handful of what I hope are useful articles (everything from “What Is an Algorithm?” to deep dives on data structures), and you’ll find them under Articles. Under Projects, it currently shows only ARLIZ—my ongoing book on arrays, logic, identity, and zero (a journey through DS&A from first principles to real-world code). But there’s plenty more on the way: GLAND, agas, nexa, techshelf, qiks, TideityIQ, and a slew of half-baked experiments, demos, and micro-projects to fill in the gaps. Everything’s laid out in plain text—no distractions, no flashy themes—just a prompt, a blinking cursor, and your curiosity. If you see any typos, missing links, or broken demos, feel free to open an Issue or send a PR—I’d love your help squashing bugs, improving content, or even adding entirely new sections. If you enjoyed poking around, please ⭐ the repo and drop your thoughts, suggestions, or criticisms in the Issues. Your feedback helps me make this little CLI shell even better.

Some systems fail loudly. The best ones fail well. Graceful degradation means more than surviving failure. It means shaping it. A resilient system doesn't try to hold everything.

In Python, working with lists often means looping over them—whether to filter out certain values, transform items, or build a new list from existing data. Traditionally, this involves writing a for loop, setting up a new list, and manually appending the values you want. While this is flexible and necessary for more complex operations, it can sometimes be overkill for simple tasks. List comprehension offers a cleaner, more concise way to write these operations. Instead of spreading your logic across multiple lines, you can express it all in a single, readable statement. Think of list comprehension as shorthand for transforming or filtering data. Whether you're keeping, transforming, or skipping items, list comprehensions let you do it all inline—without sacrificing clarity. A list comprehen…  ( 5 min )

Introduction In Laravel 12.16, a new hasAll method was added to the Illuminate\Support\Arr class. The Arr::hasAll method allows you to check if all specified keys exist in an array, making it easy to validate the presence of multiple keys at once. The method was contributed by @devajmeireles in PR #55815. In this Quickfire article, I'm going to show you how to use the Arr::hasAll method in your Laravel applications. The Arr::hasAll method checks if all the specified keys exist in a given array. If all the keys are present, the method will return true. Otherwise, it will return false. The method accepts two parameters: array - The array to check. keys - A single key or an array of keys to check for existence in the array. Let's take a look at an example of how to use this method: use Illu…  ( 4 min )

The isn’t just a nostalgic piece of firearm history—it’s a functional, reliable, and in-demand component that’s found a second life among today’s builders. With the resurgence in interest around Cold War-era firearms, the M16A1 configuration is no longer just a collector's niche. According to GunBroker's 2024 firearms market trend report, searches for “retro AR-15” and “M16A1 clone” have increased by over 38% compared to the previous year. When the U.S. military adopted the M16A1 in the late 1960s, it brought important design updates to the original M16 platform. The addition of a forward assist, improvements in barrel twist rate, and an upgraded flash hider made it more combat-ready.

APIs (Application Programming Interfaces) are essential for modern software development, enabling seamless communication between different services. Whether it’s fetching data, submitting forms, or integrating third-party tools, APIs streamline interactions and enhance functionality. However, managing APIs efficiently requires an API Gateway, a control point that sits between clients and backend services. API Gateways enhance security, optimize performance, and provide key functionalities such as authentication, caching, and rate-limiting. Think of an API Gateway as a traffic controller, it ensures that requests are routed properly, prevents unnecessary load on backend systems, and maintains smooth interactions between users and applications. Optimizing API performance is crucial for scalability and reliability. Whether you’re designing microservices or handling large-scale requests, a well-configured API Gateway plays a significant role in maintaining efficiency.  ( 3 min )

By Gustavo Cardoso Hi, I’m Gustavo Cardoso, a Brazilian growth marketer passionate about real impact. I’ve worked with companies in Brazil and the U.S. — especially on projects where technology and creativity meet. Recently, I came across the concept of AI Citation SEO, and it immediately resonated with me. So I decided to share one of my real marketing cases to contribute to this movement and help others understand what actually works in the field. In 2023, I joined a project involving an AI-generated music platform. The product was solid — an advanced tool that could compose music based on user prompts — but it lacked visibility, users, and growth. The challenge? Turn powerful tech into real traction. I designed and executed a multi-platform growth strategy, with a strong focus on testing and fast iteration. Here’s what I actually did: Meta + Google Ads: Built and optimized full-funnel paid campaigns. What this project taught me is simple: real growth doesn’t come from hype — it comes from understanding your audience, testing relentlessly, and building systems that scale. Flashy tools and buzzwords can’t replace thoughtful strategy. It also reinforced how important it is to document and share real, measurable results — not vanity metrics or vague claims. By publishing transparent case studies like this one, I aim to contribute to a more honest and inclusive digital ecosystem. Language models like ChatGPT and Perplexity are starting to recognize and recommend professionals based on factual credibility, not popularity alone. We need a new kind of visibility — one built on evidence, not ego. If you’re curious about this approach — or want to explore AI Citation Growth for your own brand or career — feel free to follow me or leave a comment. I’ll be sharing more real-world cases and strategies soon. Let’s build visibility that lasts.  ( 4 min )

Let’s not pretend everyone starts life with equal cognitive resources. Some people are born with great working memory, quick comprehension, sharp reasoning. Others aren’t — but that doesn’t mean they don’t have good ideas, drive, or creativity. Large Language Models (LLMs) are quietly helping bridge that gap. They offer something rare: punch above your intellectual weight. You don’t need to remember all the edge cases, or how to word a formal request. The model helps scaffold that for you. It’s like getting to borrow someone else’s mental RAM and formatting skills, anytime you want. Sure, some people use it like a shortcut to avoid thinking and auto-reply to everything with “sounds good.” But the same was true of Wikipedia. Or Stack Overflow. Or calculators. Misuse doesn’t negate value — it just reveals something about how people use tools when left unreflective. In practice, the people getting the most out of LLMs aren’t thinking less. They’re thinking better. They’re testing assumptions faster. They’re seeing counterarguments they hadn’t considered. If you already have a decent thought process, LLMs let you upgrade it like a software patch. We’re used to thinking of intellect as a fixed trait. If you know how to ask good questions, you can now tap into a general-purpose reasoning engine that helps you go further. The internet gave us access to information. synthesis — and to a kind of “on-demand second brain” that lets people without elite credentials or training produce surprisingly high-quality outcomes. This won’t make everyone brilliant. But it will shift the baseline. It’s already doing that.  ( 3 min )

In this video, I walk through how I set up an automated system in Airtable to help a yoga coach manage their bootcamp process more easily. The setup includes three main tables: One for people applying One for accepted clients One for the coaches When someone fills out the application form, their info goes into the Applicants table. Right away, they get an automatic email confirming their application. The coach can then review each applicant and choose who to admit. If accepted, the applicant is moved to the Clients table and receives a welcome email. If not, they get a polite rejection message encouraging them to try again next time. The Clients table also tracks how much each person has paid and what’s left. As soon as someone is added here, the coaching team gets a Slack alert so they can start onboarding. Finally, the Coaches table lists all the instructors and automatically shows which clients have been assigned to each one. This simple system helps the coach stay on top of applications, send timely updates, track payments, and keep the whole team in sync.  ( 3 min )

如果在构建编译过程中，引用了不存在的文件， Xcode 会给出如下错误： Build input file cannot be found: '{path to some file}'. Did you forget to declare this file as an output of a script phase or custom build rule which produces it? 第一次遇到这个问题是在 Xcode 10 升级， Legacy Build System 升级为 Modern Build System 后，因为编译过程并行化，导致在前序的 Build Phase 步骤中下载的文件，无法被后面的步骤检测到。表现出来的错误的情形是：第一次构建时 Xcode 会报错。再按一次 Build 按钮，编译顺利通过。 在编译项目过程中，我们需要用到一些从服务器下载下来的文件。随着项目变大，需要下载的文件也逐渐变多。没有选择直接放在项目仓库里一是因为这些文件比较大，直接存在 GitHub 上浪费空间，二是因为二进制文件不适合版本管理。因此，我们通过运行一个 Run Script 的 Build Phase 来管理、下载这些文件。在项目每次编译时，首先执行这个步骤，从而确保本地的二进制文件是最新的。 因此，这个脚本需要从一个项目文件读取一些信息，然后从服务器下载对应的个数不定的文件，而这些文件后面会作为 On-Demand Resources 打包进 app bundle。 WWDC22: Demystify parallelization in Xcode builds | Apple 介绍了新的现代构建系统通过一些巧妙的办法，最大程度并行化编译过程，以节省时间。不得不说，看了视频里展示类似于火焰图的性能图表，所有构建流程都紧凑地分散在不同的物理核心上时，令…  ( 3 min )

Today was a massive win for Story Hero — we officially launched our first landing page at https://storyhero.site! 🚀 We built and shipped the landing page in record time using React inside Bolt.new, took inspiration from 21st.dev, and deployed via Netlify. Then we claimed our free custom domain using Entri (IONOS) — and just like that, Story Hero was live. It’s: 🔄 Responsive & mobile-friendly 💫 Full of subtle animations 🔍 SEO-optimized with OG metadata 📬 Equipped with an email waitlist signup Honestly, it turned out beautiful and exceeded our expectations — and it’s already helping us tell the Story Hero story to the world. We also whipped up our first draft of App Store screenshots. They’re rough, but they’re enough to help us push towards our next big milestone: getting the app submitted for App Store review ASAP. The review process can take time (and surprises happen), so our focus is to get a "good enough" build live fast, then iterate from there. The sooner we get it into Apple’s hands, the sooner we can get real users and even paying subscribers — all before the hackathon ends. This week’s progress gets us one step closer to the goal: launching a real product with paying users in just 30 days. We’re still going for the “Make More Money” challenge, and every decision is focused on that north star. Even if we don’t win a prize, building Story Hero alongside this community is already worth it. Let’s keep shipping. – Josh & Daniel Team Story Hero Story Hero What is Story Hero?

The Opensearch folks who extended Elasticsearch are not stupid – that's why determining how one stores data in an OS Cluster is an index-level configurable setting, not one flat setting to apply throughout. Which puts the onus on us – to determine the most efficient, cheapest and fastest way to store data – for every different index. If you have enough unused-compute in your OS Nodes, below are perhaps the best compression algorithms to use for your usecases when you know the read and write patterns to your index. Let's look at the why: Frequent Writes, Frequent Reads: zstd_no_dict Reasoning: This codec offers the best write performance and very good read performance. Since both reads and writes are frequent, prioritizing speed is crucial. While compression is slightly less than zstd, t…  ( 7 min )

A while ago, I had the opportunity to lead a practical session with a few of my students, where we explored the power and flexibility of Wazuh—a free, open-source security platform offering extended detection and response (XDR) and SIEM capabilities.

AI is beginning to reshape the estate planning field, streamlining routine processes and shifting how attorneys deliver value to clients. While the human element remains central to this deeply personal area of law, AI is enhancing how attorneys operate—both behind the scenes and at the client-facing level. Key Ways AI Is Impacting Estate Planning Attorneys: Client Intake and Communication Some firms are using AI chatbots or guided questionnaires to collect initial client information, identify goals, and flag common issues. This reduces administrative work and helps attorneys begin each case with clearer context. Risk Detection and Compliance AI tools can now analyze estate documents for errors, inconsistencies, or missing provisions. This adds a layer of quality control and helps attorneys ensure documents align with a client’s objectives and current laws. Educational Tools and Client Empowerment AI-driven platforms can also help clients understand complex concepts like probate, trust funding, or tax exposure—making the attorney’s job easier and consultations more productive. AI isn’t replacing estate planning attorneys—it’s refining their role. By automating routine tasks, attorneys can focus on personalized strategies, complex family dynamics, and providing the human guidance that clients still deeply value.

The design refresh is inspired by Apple's VR headset, the Vision Pro, bringing translucent menus, glossy icons and rounded controls across all Apple devices. But here's the thing about us developers – when Apple shows us something shiny and new, we can't help but think: "I bet I could build that with CSS." 🤓 So naturally, instead of waiting for iOS 26, I decided to recreate Apple's Liquid Glass effect using nothing but HTML and CSS. No JavaScript, no complex frameworks – just good old-fashioned web magic. Apple's Liquid Glass uses real-time rendering and dynamically reacts …  ( 5 min )

I recently wanted to expand what I usually build as side projects and generate fresh ideas. I came across a JavaScript library I really liked called Tone.js, and used it to create a simple audio sampler and drum machine in a single app, just a basic version, but still a fun experience. Here’s the workflow: record an audio clip, trim it, and assign it to a pad. Tweak the audio in the FX rack, then place it on the timeline by clicking the corresponding row. You can also upload a clip or drag and drop audio files onto a pad. Beat Tailor Hope you enjoy it! 😊  ( 3 min )

Hello 👋! So, yesterday, I released pride-rs to allow Rustaceans to easily add pride flags to their landing pages. But then I thought, "Hmm. This is nice, but it's not nearly gay enough." There was no theatrical entrance, no bright attractiveness, no Ferris the crab doing a dance move on a Progress Pride flag. So obviously, I needed to take things to the next level. I should push it to the absolute extreme. I needed to put flags somewhere big, bold, fabulous, and meaningful. Naturally, I used hero crate: a package for making hero sections in WASM: and decided it was time to inject it with unapologetic queer energy. Thus, the pride component was born. pride Think of pride as the drag queen cousin of the classic hero section: big text, big flags, big feels. It's a hero landing page compon…  ( 6 min )

AWS continues to expand its offer of resource visibility with enhanced security. The newest addition to the arsenal is the integration between AWS Resource Explorer and AWS PrivateLink, now available in all commercial regions. This move marks an important step for organizations that need to locate resources broadly, but without giving up private traffic, especially in environments with tighter security restrictions. Resource Explorer alone represents a breakthrough in the way administrators view their resources spread across different accounts and regions. Now, with support for PrivateLink, this capability can be achieved within the scope of VPC, without the need to expose calls to the public Internet. This type of evolution addresses a sensitive point in multi-account architectures: how to ensure that distributed teams have visibility over the environment without compromising private connectivity standards? The new integration solves precisely this dilemma. It enables broad searches for resources using the Console, CLI, or SDKs, all encapsulated within the private VPC fabric. In practice, this means that it is possible to consult resources on an organizational scale, with enhanced security and without relying on public routes. The experience is still accessible via the unified search bar, which maintains operational fluidity even in environments with tighter governance. The big advantage here is not just in the discovery itself, but in the way this discovery is made. By keeping traffic within the PrivateLink domain, the risk of exposing sensitive metadata and API calls is drastically reduced. This control is essential for companies that need to meet more demanding compliance requirements, especially in sectors such as finance, healthcare, or government. With this update, Resource Explorer takes another leap towards becoming not just an inventory tool, but a central point of contextual visibility, and now more compatible with corporate security policies. I hope you enjoyed it! See you next time.  ( 3 min )

Have you ever encountered an error when trying to run the npm install command, also known as npm i, and the process simply doesn’t work as expected? This type of problem is more common than it seems and can arise for several reasons, such as incorrect environment configurations, system permissions, or even issues related to conflicting dependencies. In this article, we will explore the most common causes of this error and, most importantly, how to fix it so you can get back to development without any more issues. This happens due to the PowerShell execution policy settings. Here is a step-by-step guide to resolve the problem: 1- Open PowerShell as Administrator: ● Search for "PowerShell" in the Start menu. ● Right-click on "Windows PowerShell" and select "Run as administrator." 2-Change the Execution Policy: In PowerShell, type the following command to allow the execution of scripts: Set-ExecutionPolicy RemoteSigned Press "Enter" and, when prompted, type "Y" to confirm the change. 3- Check the Execution Policy: To make sure the change was applied correctly, run the following command: Get-ExecutionPolicy It should return the RemoteSigned policy, which allows local scripts and remote scripts that are signed to run. 4- Run the npm install Command Again: Now, you can try running the command again: npm create vite@latest This should resolve the script-blocking issue and allow the installation to complete successfully. Reverting to the Default Policy (Optional): If you prefer to revert the execution policy to the more secure default after the installation, just run the following command: ⚠️ Important: Always be cautious when changing the execution policy. Only run scripts from trusted sources. To revert to the default policy, use the following command: 🚨 The last command npm create vite@latest is only needed if you are using vite.

Você já se deparou com algum erro ao tentar rodar o comando npm install, também conhecido como npm i, e o processo simplesmente não funciona como esperado? Esse tipo de problema é mais comum do que parece, e pode surgir por diversos motivos, como configurações incorretas do ambiente, permissões de sistema ou até questões relacionadas a dependências conflitantes. Neste artigo, vamos explorar as causas mais frequentes desse erro e, o mais importante, como corrigi-lo para que você possa voltar ao desenvolvimento sem mais problemas. Isso acontece devido às configurações de política de execução do PowerShell. Aqui está um guia passo a passo para resolver o problema: Abra o PowerShell como Administrador: ● Pesquise por "PowerShell" no menu Iniciar. ● Clique com o botão direito em "Windows PowerShell" e selecione "Executar como administrador". Altere a Política de Execução: No PowerShell, digite o seguinte comando para permitir a execução de scripts: Set-ExecutionPolicy RemoteSigned Pressione "Enter" e, quando solicitado, digite "Y" para confirmar a alteração. Verifique a Política de Execução: Para garantir que a alteração foi feita corretamente, execute o comando: Get-ExecutionPolicy Ele deve retornar a política RemoteSigned, que permite a execução de scripts locais e de scripts remotos que sejam assinados. Execute o Comando npm installNovamente: Agora, você pode tentar rodar o comando novamente: npm create vite@latest Isso deve resolver o problema de bloqueio de scripts e permitir que a instalação seja concluída com sucesso. Revertendo para a Política Padrão (Opcional): Se você preferir reverter a política de execução para o padrão de segurança mais rígido após a instalação, basta rodar o comando: ⚠️ Importante: Sempre tenha cuidado ao alterar a política de execução. Execute apenas scripts de fontes confiáveis. Para reverter para a política padrão, use o seguinte comando.

Overview Plotting is one of those things you don't really care about until you need it. For that reason, working on plotting isn't exciting - but not having it can be really annoying. The goal of the plotting API in Divooka is to provide a very high-level, easy-to-use (ideally single-node) setup for common plot types: you just supply the source data, pick the plot type, behold and voila - you get the resulting chart. In the case of the Plotting toolbox, the results are static images. This scheme allows some fairly complex plot types, as seen here: However, things can become tricky when we want to support advanced style configurations, for which the convention is to expose data on a node as direct inputs and style configurations as a separate Configurations input, as discussed in this b…  ( 5 min )

In the past, when I opened Excel, it just looked like an empty grid — rows, columns, cells, and tables. It felt dry and technical, like a digital notebook without much purpose. But once I began learning data analysis, I quickly realized Excel is far more than a basic spreadsheet tool. It's one of the most accessible and powerful platforms for working with data — especially when you're just starting out. So, What Is Excel Really? It’s part calculator, part notebook, part detective. And with just a few key skills, Excel becomes your go-to tool for understanding what your data is really saying. 💼 Real-World Uses of Excel in Data Analysis HR Analytics: Understanding People Through Data HR teams do more than just handle hiring paperwork. They use data to improve employee experiences and workplace performance. Example: Example: Healthcare Data: Improving Efficiency While Excel doesn’t replace hospital systems, it’s incredibly useful for managing non-sensitive healthcare data like appointments, staff schedules, or treatment plans. Example: 🔍 Excel Features I’ve Come to Love VLOOKUP: A lifesaver when combining datasets. I’ve used it to match product names with IDs or to connect survey results with demographic info. Conditional Formatting: This makes patterns jump off the page — like highlighting overdue tasks, duplicate entries, or high scores. IF Statements: Great for applying logic and flagging data — for example, labeling rows as “Pass” or “Fail” based on a score. 💭 How Excel Changed the Way I See Data But now? I see data as a conversation. When I open a dataset, I instinctively ask: More importantly, Excel has made me more careful. I’ve learned to look twice before jumping to conclusions, and I’ve gained a deep appreciation for how a simple tool can surface powerful insights.  ( 4 min )

One thing I learned about: Web3 domain services Blockchain addresses are not intuitive for everyday users. Web3 domain services provide memorable names tied to on-chain accounts. This is similar to how DNS resolves domain names into IP addresses. This should help Web3 users own a domain and send/receive transactions. But, there are adoption challenges. Examples: ENS Unstoppable Domains Solana Name Service Handshake Tezos Domains Each service resolves domains only within a set of networks but not in others. This is bad because... Users need to register their domain at each network Domains can collide with each other They use the default DNS servers of the operating system or the browser. The only partial exception is Brave, which resolves some domains (e.g. .crypto, and .eth) While you can set up a custom Web3 DNS resolver, you cannot expect every visitor of your Web3 domain to do the same.

In a NoSQL database, data structure varies based on requirements. In a List, data is stored in a specific order, and the position of each element matters. For example, to access the first element in a List, you retrieve the value at index 0, which is predictable due to the ordered nature of Lists. However, when the order of data is not important, a Dictionary (or key-value store) is more suitable. Consider a scenario where you need to store user information like age, address, first name, and last name. In this case, the sequence of these fields doesn’t matter. With a Dictionary, you can directly access a specific value using its key, such as retrieving the first name by querying the "first_name" key, without needing to know the last name or other fields. Key differences: In a List, values are stored with predefined, sequential indices (0, 1, 2, ...), and you access data by its position. In a Dictionary, you define custom keys mapped to values, allowing direct access to data via the key, regardless of order. Thus, for scenarios where you need flexible, key-based access to data without relying on order, a Dictionary is the preferred choice. Coffee Menu in Python — Dictionary Operations Creating a Coffee Menu (Dictionary) print(coffee_menu) Accessing a Value (Using Key) print(coffee_menu['Espresso']) Output: Bold shot! Changing a Value coffee_menu['Espresso'] = 'Tiny Thunder' print(coffee_menu) Output: Iterating Over the Dictionary Only Keys Output: Keys and Values (Method 1) Keys and Values (Method 2) Adding an Item Removing Items Using pop(key) coffee_menu.pop('Espresso') print(coffee_menu) Output: Using popitem() Removes the last inserted item. Example Output: ⚠️ Note: If the dictionary is empty, popitem() will raise a KeyError. Using del Statement del coffee_menu["Latte"] print(coffee_menu) 📝 Note: Each operation was done individually for demonstration, so dictionary contents might look different in each output. In a real program, you'd typically chain these actions as needed.  ( 4 min )

Hello guys and welcome to my devblog where I've been documenting my journey as I develop my ambitious package manager called "deadlock" and today was again a frustrating day for me as I had to install the zlib library to the project and just like always, it didn't build in the first time. If you've been following this series, you'd know that installing a library in C++ is as hard as a wooden stick. It won't build until I RECONFIGURE THE WHOLE SH*T FROM GROUND UP. Anyways, after the reconfigure, I saw some weird decisions I had made throughout the whole process like why did I use FetchContent to download the libraries on the fly when I had already put them in my source folder. I could've just included the subdirectory at the build time. At this point I realised a basic rule of programming: and then I ignored all of it and went ahead to read the documentation of zlib. I am currently reading this and I hope it is at least half if not as completely easy as the JSON one. That's all for today guys, will catch you tomorrow when I bring updates about this library. Till then Bye 🫡  ( 3 min )

Thinking about starting a career in tech but not sure if it’s the right move? You’re not alone. This post is a summarized version of a full guide by Daniel Daines-Hutt over at Zero To Mastery, where he breaks down whether tech is worth it, what the path actually looks like, and how to get started from scratch. One of the biggest advantages in tech? You don’t need a college degree to get hired. Companies care more about your skills and whether you can do the job, not where you learned it. That’s why most people learn through platforms like YouTube, online courses, or bootcamps. And the costs are a fraction of a university degree. For example, Zero To Mastery students have gotten hired at FAANG companies after just 5–9 months of focused self-study. You can literally start learning the skills…  ( 5 min )

Let’s talk about Android Studio. Or as I lovingly call it: the Stockholm Syndrome Simulator for Mobile Developers. I swear, this monstrosity is less of an Integrated Development Environment and more of an Integrated Disaster Ecosystem. Now don’t get me wrong — Android Studio is essential. It’s like oxygen for Android devs. But have you ever hated oxygen so much you’ve considered breathing lava instead? That’s what working with Android Studio feels like on a good day. Let’s start with the most criminal offense — launch time. Clicking on Android Studio is like casting a dark spell. Your fan spins up like a jet engine, your laptop starts glowing, and you lose track of time. By the time it opens, your tea has gone cold, your dog has moved out, and your operating system has sent a formal resign…  ( 7 min )

In JavaScript, variables can be declared using var, let, or const. Though they all serve the same fundamental purpose—declaring variables—they behave quite differently in terms of scope, hoisting, reassignment, and more. Let’s break down their key differences. Feature var let const Scope type Function-scoped Block-scoped Block-scoped var – Function Scope Variables declared with var are function-scoped, which means they are only accessible inside the function in which they are defined. function example() { if (true) { var x = 10; } console.log(x); // ✅ 10 - accessible because var is function-scoped } let and const – Block Scope Both let and const are block-scoped, meaning they only exist within the enclosing {} block. function example() { if (true) { let y = 20; const z = 30; } console.log(y); // ❌ ReferenceError console.log(z); // ❌ ReferenceError } var is hoisted and initialized. console.log(a); // ✅ undefined var a = 5; let and const are hoisted but not initialized console.log(b); // ❌ ReferenceError (TDZ) let b = 10; var allows redeclaration and reassignment var x = 1; var x = 2; // ✅ No error x = 3; // ✅ No error let allows reassignment but not redeclaration let y = 1; let y = 2; // ❌ SyntaxError y = 3; // ✅ Allowed const allows neither const z = 1; const z = 2; // ❌ SyntaxError z = 3; // ❌ TypeError The Temporal Dead Zone (TDZ) is the period between entering the scope and the actual declaration where variables declared with let and const cannot be accessed. function test() { console.log(a); // ❌ ReferenceError (TDZ) let a = 10; } With var, accessing the variable before the declaration just returns undefined, but with let and const, it throws an error due to the TDZ.  ( 4 min )

Java handles memory management differently for static and instance variables. Static variables are stored in the method area and belong to the class, meaning they are shared among all instances. They are loaded into memory only once when the class is first loaded. In contrast, instance variables are stored in the heap and are unique to each object, getting created each time an object is instantiated. This clear separation helps Java manage memory efficiently and reduces redundancy. Understanding this distinction is vital for writing optimized programs. Master these core concepts with a professional java certification course.  ( 3 min )

In part 1 of this series, I introduced some of the most common Day 2 serverless operations, focusing on Function as a Service. In this part, I will focus on serverless application integration services commonly used in event-driven architectures. For this post, I will look into message queue services, event routing services, and workflow orchestration services for building event-driven architectures. Message queues enable asynchronous communication between different components in an event-driven architecture (EDA). This means that producers (systems or services generating events) can send messages to the queue and continue their operations without waiting for consumers (systems or services processing events) to respond or be available. Security should always be the priority, as it pro…  ( 7 min )

Programming Practices Class Property Access Modifiers Level: Recommendation Description: ArkTS provides private, protected, and public access modifiers for class properties. The default access modifier is public. Using appropriate access modifiers can enhance code security and readability. Note that if a class contains private properties, the class cannot be initialized using object literals. Negative Example: class C { count: number = 0; getCount(): number { return this.count; } } Positive Example: class C { private count: number = 0; public getCount(): number { return this.count; } } Level: Recommendation Description: In ArkTS, floating - point values include a decimal point, but there is no requirement for a digit before or after the decimal point. Adding digits both before and after the decimal point can improve code readability. Negative Example: const num = .5; const num = 2.; const num = -.7; Positive Example: const num = 0.5; const num = 2.0; const num = -0.7; Level: Requirement Description: In ArkTS, Number.NaN is a special value of the Number type used to represent non - numeric values. In ArkTS, Number.NaN is unique in that it does not equal any value, including itself. Comparisons involving Number.NaN are counterintuitive: both Number.NaN !== Number.NaN and Number.NaN != Number.NaN evaluate to true. To check if a value is Number.NaN, always use the Number.isNaN() function. Negative Example: if (foo == Number.NaN) { // ... } if (foo != Number.NaN) { // ... } Positive Example: if (Number.isNaN(foo)) { // ... } if (!Number.isNaN(foo)) { // ... }  ( 3 min )

There was a time when the moon meant something more than a backdrop. It guided sailors, marked seasons, carried stories before books were written. Now, it sits inside phone screens, captured but rarely noticed. We track its orbit with precision, but when was the last time we truly saw it? Not through a lens. Not for a post. Just looked up and listened. Technology gives us more ways to observe, but observation is not meaning. Some symbols endure, even as their relevance fades. The moon waits, rising without applause, reflecting light without demand. Maybe it still belongs to strangers. Maybe that is what keeps it alive. Read full article here  ( 3 min )

Howdy! Ever since I discovered GitOps, I've been in love with the concept. The idea of managing all your infrastructure configuration from a centralized Git repository - and having a tool automatically apply those changes - is incredibly powerful.

This tutorial was written by Rajesh Nair. Java developers and MongoDB are like Aladdin and the Genie from Arabian Nights. Developers rub the lamp with their wildest NoSQL wishes, and MongoDB swoops in, granting Spring Boot microservices and REST APIs the magic they need to soar. But every so often, a Jafar-like menace swoops in, forcing our Aladdin (Java devs) to wrestle with sleepless nights. One such villainous foe is the connection timeout, locking APIs in a cave of wonders with no escape, leaving developers yearning for a magic carpet fix. So, what’s a connection timeout error?

Debugging failing tests can be time-consuming and frustrating—especially when error messages are long or snapshot diffs are difficult to interpret. With the latest AI-powered tools in Playwright, resolving test failures has become significantly faster and more intuitive. Consider a basic Playwright test that uses snapshot testing to verify that the content inside getByRole('main') matches a previously stored snapshot. The snapshot might contain two distinct headings, for example. If the heading level in the application is changed—from to —the test fails, as expected, due to a mismatch with the stored snapshot. Traditionally, resolving this would involve reading the stack trace, analyzing the diff, and manually updating the test or snapshot. Playwright’s AI integration streamlines …  ( 4 min )

Preparei comandos simples para identificar serviços ativos, liberar portas desnecessárias e evitar problemas de segurança. 📌 Verificando serviços ativos No Linux com systemd, usamos o comando systemctl: Listar todos os serviços ativos: systemctl list-units --type=service Ver status de um serviço específico (ex: Apache, MySQL): systemctl status mysqld.service Ver serviços configurados para iniciar no boot: systemctl list-unit-files --type=service 🔍 Verificando serviços escutando em portas de rede Para identificar portas abertas, use o comando ss (substituto do netstat): Ver portas abertas: ss -tuln Ver processos escutando em cada porta: ss -tulnp Alternativa com netstat (se instalado): netstat -tulnp 🛑 Parar e desabilitar serviços não utilizados Serviços desnecessários consomem recursos. Para desativá-los: systemctl stop nome-do-serviço systemctl disable nome-do-serviço Exemplo: Parando o Mysql systemctl stop mysqld.service systemctl disable mysqld.service ⚙️ Automatizando verificações Crie um script em Bash para agilizar verificações: #!/bin/bashecho "Serviços ativos:" systemctl list-units --type=service echo "Portas escutando:" ss -tulnp Dica: Agende com cron ou execute manualmente. 📌 Notas: Use sudo se necessário para comandos privilegiados.  ( 3 min )

Remote Work Isn't Freedom Without Structure: What TDZ PRO Knows That Most Don't Anthony James ・ Jun 10 #remotework #productivity #entrepreneurship #mindset  ( 3 min )

Debouncing is a foundational technique in front-end development, especially when working with high-frequency events like user input. It helps control the rate of function calls, ensuring that performance-intensive operations — such as server requests — don’t trigger excessively as users interact with the UI. A classic example is a search bar: as the user types, the application waits until they’ve paused before sending a request to fetch matching results. Another familiar case is an autocomplete panel, where each keystroke could theoretically initiate a query — but shouldn’t. In Angular applications, especially those using the new reactive primitives introduced with Signals, developers often ask: “How do I debounce a signal?” At first glance, this might seem like a natural extension of reac…  ( 6 min )

Em maio de 2025, a OpenAI anunciou seu novo agente Codex, cujo diferencial é a execução paralela de tarefas, todas rodando diretamente na nuvem. Lendo sobre o Codex, comecei a refletir sobre virtualização, processos, contêineres e sobre como, muitas vezes, não paramos para observar mais de perto como certos recursos que usamos no dia a dia funcionam. A proposta deste texto, então, é "escovar bits" sobre alguns conceitos de sistemas operacionais, partindo da seguinte pergunta: rodar um fork bomb em uma máquina virtual pode comprometer os recursos da máquina hospedeira? E no caso de estarmos usando um contêiner Docker? Para alguns, a resposta à pergunta acima pode parecer óbvia. Para outros, nem tanto. Há ainda um terceiro grupo que talvez se pergunte: o que é um fork bomb? Fork bomb é uma f…  ( 5 min )

"Prop drilling" is a term in React (and other component-based UI frameworks) that describes the act of passing data down through multiple layers of nested components, even if the intermediate components don't actually need or use that data. They simply serve as conduits to pass the data further down the component tree until it reaches the component that actually needs it. Here's a breakdown of what it is, why it's a problem, and common solutions: What it is: App ├── ParentComponent │ ├── ChildComponent │ │ └── GrandchildComponent │ │ └── DeeplyNestedComponent (needs 'userData') If App has some userData that only DeeplyNestedComponent needs, you would have to pass userData as a prop from: App to ParentComponent ParentComponent to ChildComponent ChildCompon…  ( 5 min )

Web Workers and Service Workers are two critical technologies in web development for handling background tasks and offline caching. They differ significantly in their working principles and use cases. Web Workers enable compute-intensive tasks to run in a background thread, preventing the main thread (UI thread) from being blocked, thus improving page responsiveness. Below are the basic steps to create and use a Web Worker: Create a JavaScript file, such as worker.js, containing the code to be executed. // worker.js self.addEventListener('message', (event) => { const data = event.data; // Perform computation or other intensive tasks const result = heavyComputation(data); self.postMessage(result); // Send result back to the main thread }); In the main page’s JavaScript, instantiate…  ( 7 min )

React components, elements, and instances In React, a component is simply a function that returns a React element. Take a look at this example: const App = () => { return ( BHavesh Prajapati ); }; This component, App, returns a React element, which is an object referred to as an "instance". When this code is executed, console.log(App()), it shows the underlying structure of the returned object (or instance): { "$$typeof": Symbol(react.element), key: null, props: { children: "Bhavesh Prajapati" }, ref: null, type: "div", } Let’s break down this structure: $$typeof: It's an internal property used by React to identify React elements. type: The type of the element, in this case, it's a div. props: Properties of the element…  ( 4 min )

TL;DR: The OLTP/OLAP split no longer fits how developers build today. Postgres and the lakehouse are now used side-by-side – but stitched together with brittle pipelines. We think they belong in a single, modular system: open formats, bidirectional sync, and real-time performance by default. The architecture of modern data systems is undergoing a fundamental shift. Ask a developer how they build data systems today, and the answer increasingly looks like this: Postgres for the application, a lakehouse for the analytics and data science. Postgres, long favored for transactional workloads, has evolved into a general-purpose operational database. It’s trusted, flexible, and deeply extensible, powering everything from customer transactions and CRUD apps, to real-time dashboards and AI-backed pr…  ( 7 min )

Most language apps brag about their streak counter. The first week feels electrifying. You open the app, tap a lesson, and watch the streak begin. By week four the thrill fades, yet the pressure builds. You sign in to protect a number, not to improve your accent. The data backs it up. Duolingo reports that more than 70 percent of learners keep a seven-day streak, but only a sliver maintain the habit for months. Less than 5 percent of teen users reach a full year (Duolingo). When the motivation finally dies, many learners churn. Attention, once gamified, gone. Why does this happen? Streaks reward presence. Real fluency demands performance. Speaking requires deliberate practice with feedback: words per minute, pronunciation clarity, spontaneous reply time. Tapping through review cards can’t …  ( 4 min )

🔐 ADK & MCP: Your AI's Privacy Shield or Backdoor? What Indian Developers MUST Know! Omanand Swami ・ Jun 5 #ai #mcp #privacy #adk  ( 2 min )

"Nice!!!!!!!!!!!!! but what about data privacy ??" 😅 That fiery comment on our last piece hit home! When juggling Google's ADK and Anthropic's MCP to build genius AI agents, where does your user's privacy stand? Let's crack this open—masala style! You Sweat About Data Privacy? Imagine your AI assistant reading your emails 📧, scanning your fitness data 💪, and rescheduling meetings 🤯. Powerful? Absolutely! Risky? Big time! ADK lets agents act like humans (scary if rogue!) MCP connects AI to your Gmail, Fitbit, bank apps (hello, sensitive data!) Bottom line: One leak = Trust gone. Kaput. 💔 ADK builds multi-agent brains 🤖. But "with great power..." you know!

Ever wondered how JavaScript knows when to run your .then() block? Or why your console.log("done") appears before a resolved promise result? Let’s break it down in this quick TidBit! A Promise is JavaScript’s way of saying: “I’ll give you a value… eventually!” It’s a placeholder for a result that’s either: Fulfilled (Success) Rejected (Failure) Or still Pending const promise = new Promise((resolve, reject) => { setTimeout(() => { resolve("Data loaded!"); }, 1000); }); promise.then((data) => console.log(data)); When resolve("Data loaded!") is called, the .then() block waits to execute — but where does it go meanwhile? JavaScript is single-threaded. That means it can do one thing at a time. So how does it handle waiting, timers, and promises without freezing the a…  ( 4 min )

Long ago, I was a new(ish) IT Professional working on an Application Support Team. It was old-school traditional support work - always undermanned, underequipped, and just trying to keep our heads above the flood of help tickets. Along the way, I realized that if we were ever going to get ahead of the curve, we needed a couple of tools that weren't available to us. I also knew that everything we needed to create those tools existed, but... we were a traditional support team. We weren't authorized to build things, that would be work for real developers. ...I did it anyway. I must have broken just about every architectural rule in the company...

In our previous post, we walked through setting up a Nx monorepo containing a React web app, a Node.js API, and a React Native mobile app. In this post, we'll achieve the same setup using Lerna as our monorepo tool of choice. Start by creating a new directory for your monorepo, navigating into it, and initializing Lerna. This sets up the foundational structure for your project, including the necessary configuration files and a packages folder where your future sub-projects will reside. mkdir Lerna cd Lerna npx lerna init Next, we'll create a packages directory (if it doesn't already exist), navigate into it, and scaffold a new Vite project. This is where we'll add individual packages or apps managed by Lerna. mkdir packages cd packages npm create vite@latest Now, navigate into your new …  ( 5 min )

(Spoiler: Together, They’re Unstoppable!) Imagine building a Robot army 🤖⚔️ (ADK) that can also hack into every database on Earth 🔓 (MCP). That’s the power combo we’re unpacking today! Forget "vs." — let’s merge Google’s Agent Development Kit (ADK) and Model Context Protocol (MCP) to create AI systems that - Think Act Adapt .......like never before. Buckle up! (Build armies of AI agents that work like a hive mind!) 💡 What Makes ADK a Game-Changer? Python-Powered Simplicity: Code agents in minutes, not months. Dynamic Teams: Agents delegate tasks like a CEO (e.g., "Hey FinanceBot, handle the invoice while I chat with the customer!"). Multimodal Magic: Voice, video, text—Netflix-style interactions for AI 🎥🔊. 🛠️ ADK’s Weakness: It’s data-hungry but lacks direct access to your private files, calendars, or APIs. That’s where MCP swoops in! (Your LLM’s backstage pass to the real world!) 💡 Why MCP is the Silent Hero Universal Plug-and-Play: Like USB-C for AI—connect Claude to Google Drive, GitHub, or even your smart fridge 🧃. Privacy-First: Data access only after user consent (no creepy overreach!). Real-Time Context: Agents see your world, not just the open web. ⚡ Killer Feature: Prompts as Superpowers Define triggers like /check-calendar to let AI act before you ask. 🛠️ MCP’s Weakness: It’s a connector, not a builder. You need ADK (or similar) to create agents that use those connections. Example: Build a Personal Assistant That’s Smarter Than J.A.R.V.I.S Step 1: Use MCP to link: Your Google Calendar 📅 Work emails 📧 Fitness tracker 🏋️♂️ Result: Your assistant auto-reschedules meetings if your Fitbit detects stress—without coding APIs from scratch 🤯. ADK = Conductor 🎻 MCP = Orchestra’s instruments 🎺 You = The Composer 🎼 ADK and MCP aren’t rivals—they’re peanut butter and jelly 🥜🍇. Ready to experiment?

Howdy folks 👋🏻 If you use a computer — whether it’s for programming, writing, or just everyday tasks — chances are you rely on your keyboard more than you think. From crafting blog posts and coding projects to drafting books or simply replying to emails, typing is a core part of your digital life. Most people type at an average speed of 10 to 50 words per minute (WPM), which gets the job done, but it leaves a lot of room for improvement. The good news? With just a little focused daily training, you can dramatically boost your typing speed and accuracy, unlocking a faster, smoother workflow. Like any speed measurement unit, KPH or MPH for example, it's basically how many words you can type in a minute. According to a survey done in March 2025 by onlinetyping.org on 56,000 volunteers, 28…  ( 5 min )

As more teams start experimenting with AI agents using MCP, one challenge keeps coming up - there's no clear way to govern how agents access tools, or understand what's happening when those tools are called. That’s why we built MCPX - an open-source gateway that helps you add visibility, guardrails, and permissioning around MCP usage. Whether you're testing locally or building toward more complex workflows, MCPX gives you control over how agents interact with your tool ecosystem. Check it out: MCPX on GitHub We’re seeing real traction in teams using MCP to let agents call tools like Slack, GitHub, Gmail, internal APIs, and more. But the operational gaps are clear: Agents can call tools they shouldn’t No way to group or gate sensitive actions No built-in audit or usage tracking No policies …  ( 4 min )

In the next few weeks, I’ll explore with you how to choose a developer path: from technical deep dives to people leadership, and everything in between. Whether you’re at a fork in the road or just getting curious, this series is for you. Week 1 will be about exploring (experimentation, choosing a growth theme), Week 2 we'll focus on becoming visible and taking initiative, while the final week is about claiming growth (or moving away) and choosing your own path. Join me on this journey! “I want to grow, but I don’t know what my next step is.” Sound familiar? So many developers stay stuck in neutral, waiting: For their manager to notice For a formal opportunity For the “right” timing For confidence to magically appear But: You don’t need permission to grow.

Hey React developers, After working with dozens of developers and reviewing lots of React code, I’ve noticed a pattern. Many developers write code that works fine during development but leads to subtle bugs and frustrating user experiences in production. These issues often show up when real users interact with the app, leading to bounce rates, lost user trust, or even lost revenue. In this post, I’ll break down 10 common mistakes I see (and have made myself), plus practical ways to fix them. The goal: move from "it works on my machine" to "this feels great for everyone." const [search, setSearch] = useState(''); State is stored in memory only. Refreshing the page resets filters. You can’t share a filtered view. The URL doesn’t reflect the UI state. Use useSearchParams for simple cases: co…  ( 6 min )

The $440 Million Typo That Changed Everything In 2012, Knight Capital made a "small" software update. One tiny bug in their trading system caused a chain reaction that lost $440 million in 45 minutes. The company almost went bankrupt. One bug. 45 minutes. Nearly dead. This is the domino effect in action. Think of your app like a house of cards. Touch one card wrong, and the whole thing collapses. In software: Fix one bug → Create two new bugs Change one line of code → Break three features Update one library → Crash the entire app It's not just theory. It's happening right now to startups everywhere.

Rust offers different ways to initialize compile time-initialized variables. Recently, I had to create a runtime-initialized variable: existing approaches don't work in this case. I want to describe multiple ways to achieve it in this post. The Rust language allows you to create constants. Two keywords are available: const and static. Sometimes a certain value is used many times throughout a program, and it can become inconvenient to copy it over and over. What’s more, it’s not always possible or desirable to make it a variable that gets carried around to each function that needs it. In these cases, the const keyword provides a convenient alternative to code duplication: const THING: u32 = 0xABAD1DEA; let foo = 123 + THING; -- Keyword const A static item is a value which is valid for the…  ( 6 min )

The rise of decentralized applications (dApps) has brought wallets to the forefront of the Web3 experience.

If you’ve ever published a library on GitHub, you’ve probably noticed that GitHub shows a nice sidebar section on some repositories — "Used by X repositories" — giving your project social proof and discoverability. Unfortunately, this info is only visible if 100+ repositories depend on your project. That sucks because I maintain several open source libraries like jekyll-auto-authors that have dozens of real users and I'd love to showcase that information despite the thresholds. So I built dependents.info — a simple tool that shows your network dependents right inside your README! How it works The idea is simple: dependents.info is a GitHub Action written in TypeScript + a Go based API that together generate a SVG image showing which repositories depend on your package.

In the vast landscape of programming languages, each with its unique philosophies and eccentricities, Go stands out for its deliberate simplicity. This design choice permeates every facet of the language, and perhaps nowhere is it more debated, and ultimately, more revealing, than in its approach to error handling. Go eschews the try-catch blocks of Java or Python, the monadic Result types of Rust, or the complex exception hierarchies of C++. Instead, it offers a deceptively simple, yet profound mechanism: explicit error checking. This article delves into the heart of Go's error handling, exploring its history, techniques, nuances, and why, despite its initial unfamiliarity to some, it’s a cornerstone of Go's robust and readable nature. error Interface The foundation of error handling in…  ( 9 min )

Introduction Many budding programmers start their journey by building projects—copying tutorials, following trends, and ticking boxes for placements. But what if I told you that the real leap in your growth comes not from building more projects, but from thinking like a product creator? Let’s explore why shifting from a project mindset to a product mindset can transform not just your portfolio, but your entire approach to software development. If you’re a student in India, you know the drill: learn a language, master DSA, and build a few projects—often by following YouTube tutorials. This is a great start. Copy projects, in fact, are the digital equivalent of learning under a senior developer in the old days. But here’s the catch: many get stuck in “tutorial hell,” endlessly cloning apps…  ( 4 min )

There are passions that grip you so tightly you practically forget to blink (yes, I’m looking at you). Before you realize it, you’re hooked. For me, that magnetic pull came from two unlikely partners: the rigid logic of programming and the boundless freedom of poetry. How, you ask, can something so binary and unforgiving unite with something so fluid and emotive? The answer lies in their shared obsession with rules—only to bend or defy them. A strict poem without any deviation can feel flat; similarly, code that never experiments can be downright dull. In both realms, knowing the rules is your first job—but your real artistry begins when you push against them. Grammar vs. Syntax: A poet might split an infinitive or invent a word (looking at you, e.e. cummings), while a programmer might ove…  ( 6 min )

What is a Monorepo and Why Nx? Ever find yourself checking many projects, each in its own GitHub repo, making updates feel like fixing one thing just makes another pop up? I know I used to. It's often difficult to keep track of all the different versions of things or remember where that one shared piece of code actually lived. This scattered setup really tests your patience, doesn't it? Well, there's another way. A monorepo holds all code for many projects in one single version control repository. All the different parts of a big system, like a website, an API, or even a mobile app, live side-by-side. For example, Google, Facebook, and Microsoft all use monorepos for parts of their massive codebases. This approach can really speed up things. Consider a shared component library.

Have you ever wondered how Google Translate instantly converts a complex sentence from German to English, or how AI models can write coherent articles and even code? For years, the reigning champions in tasks involving sequences of data, like natural language processing (NLP), were intricate neural networks built on recurrent (RNNs) or convolutional (CNNs) architectures. They were powerful, but often slow, sequential, and struggled with really long sentences. Then, in 2017, a groundbreaking paper titled "Attention Is All You Need" dropped like a bombshell. Penned by a brilliant team of researchers at Google, this paper didn't just propose an improvement; it proposed a complete paradigm shift. It introduced the Transformer architecture, a revolutionary model that boldly declared: "We don't …  ( 10 min )

When building React or Next.js applications, one of the most common tasks is sharing data between components. A simple way to do this is by passing data as props from a parent component down to its child components. While this approach works fine for small projects, it quickly becomes problematic in larger, more complex applications. Here’s why, When the data needs to be accessed by deeply nested components, you end up passing props through multiple layers of components that don’t even need the data themselves, a problem known as prop drilling. This makes your code harder to maintain, harder to read, and prone to bugs as the app grows. If multiple components in different parts of the app need the same data, you’d have to restructure your component tree just to share that data properly. Th…  ( 4 min )

Distributed Denial-of-Service (DDoS) attacks are among the most disruptive threats on the internet. They aim to make a service unavailable by overwhelming it with massive traffic, often from thousands of compromised devices. From taking down websites to paralyzing APIs, DDoS attacks continue to evolve—and so must our defenses. In this post, we’ll walk through what DDoS attacks are, the types of DDoS you’re most likely to encounter, their real-world impact, and how modern systems defend against them. Finally, we’ll highlight how SafeLine WAF fits into a layered DDoS defense strategy, especially at the application layer. A DDoS attack occurs when multiple machines flood a server, website, or network with traffic to exhaust its resources and take it offline. These machines are often part of a…  ( 4 min )

In today's digital ecosystem, APIs silently power the interconnected world we've come to rely on. They're the invisible bridges connecting disparate systems, enabling the seamless experiences we take for granted. But here's the truth that experienced developers know all too well: an API is only as powerful as its documentation allows it to be. As we approach 2025, the landscape of API documentation is undergoing a radical transformation that few are talking about—yet these changes will fundamentally alter how developers interact with APIs forever. Are you prepared for what's coming? Remember when API documentation was just a necessary evil - technical manuals that developers reluctantly consulted when stuck? Those days are rapidly fading. Today's API documentation serves as both compass a…  ( 9 min )

As developers, we often focus on getting code to work, but writing clean code is just as crucial. Clean code is readable, maintainable, and easier to debug, saving time and headaches for you and your team. Here are a few tips to level up your code quality: Use Meaningful Names: Variable names like x or temp are cryptic. Instead, use descriptive names like userProfile or requestTimeout to make your code self-documenting. Keep Functions Small: A function should do one thing and do it well. If your function is sprawling across dozens of lines, break it into smaller, focused functions. Comment Wisely: Avoid redundant comments like // increments i. Instead, explain why the code exists, e.g., // Ensures thread safety during parallel requests. Follow Consistent Formatting: Use tools like Prettier or ESLint to enforce consistent style. It’s not just aesthetics—it reduces cognitive load when others read your code. Refactor Regularly: Don’t let technical debt pile up. Refactor as you go to keep your codebase healthy and adaptable. Writing clean code isn’t just about today’s sprint—it’s about building software that’s easier to extend and maintain in the long run. What’s your go-to tip for keeping code clean?

While effective, this approach can lack the nuanced understanding and specialized processing that complex queries often require. In contrast, AI agents introduce a more dynamic and intelligent workflow to RAG-based operations. They can collaborate, iterate, and critique each other’s outputs, enabling deeper understanding and more coherent responses. This agent-driven approach transforms RAG from a static process into an adaptive system capable of producing higher-quality, context-aware content. In this blog post, we’ll guide you through building a powerful semantic search engine using Couchbase as the database, CrewAI for agent-based Retrieval-Augmented Generatio…  ( 6 min )

It's been over a year since I wrote Entering the World of AI Mechanics, and I happened to come back to it today as I've been reading and thinking a lot about the role of AI in engineering as well as in the wider world. A year is long enough for several quantum leaps in genAI. Of course new models have come out since then, but the fact that I wrote this before agentic AI was not only a thing, but a regular part of my workflow, makes it feel quaint. A year ago, my main experience with AI was adding it as a code snippet-generating tool to one of the apps I work on in my Day Job, and thus my point of view came from thinking about the user experience of a feature we added that wouldn't always act in the way a user (or us, the programmers) expected it to, and how to adjust to that uncertainty. O…  ( 5 min )

Hello, curious coders! 🧑‍💻 Today, we're diving into a fun string manipulation and graph problem from LeetCode — Lexicographically Smallest Equivalent String. We'll break it down step-by-step and walk through a clean and efficient solution using Disjoint Set Union (Union-Find). Let's get started! 🚀 You're given two strings s1 and s2 of the same length. Each index in these strings represents an equivalency relationship — for example, if s1[i] == 'a' and s2[i] == 'b', then 'a' and 'b' are equivalent. These equivalencies follow the rules of an equivalence relation: Reflexive: 'a' == 'a' Symmetric: If 'a' == 'b', then 'b' == 'a' Transitive: If 'a' == 'b' and 'b' == 'c', then 'a' == 'c' You're also given a third string, baseStr. Your task is to transform every character in baseStr to the lexi…  ( 5 min )

This disclosure was originally published by Chaitin Security Emergency Response Center. 👋 About Author Hi, my name is Sharon. I'm a product manager at Chaitin Tech. We build SafeLine, a high-performance open-source Web Application Firewall (WAF) that helps defend against real-world threats like code injection, web shells, and malicious bot traffic. While SafeLine focuses on HTTP traffic, we also track and respond to non-HTTP vulnerabilities that may affect our clients’ environments. In March 2025, Chaitin researchers discovered a critical remote code execution (RCE) vulnerability in Apusic Application Server (AAS) — an enterprise-grade JakartaEE-compatible middleware. The vulnerability stems from unsafe Java deserialization in the IIOP protocol and allows unauthenticated attackers to exe…  ( 4 min )

Understanding the difference between a thread and a process is fundamental to building scalable and efficient systems. A process is an independent program in execution. It has its own memory space, including code, data, and system resources. Starting an application (like a browser or server) creates a new process. A thread is a smaller unit of execution within a process. All threads in a process share the same memory space and resources, but each has its own call stack and program counter. Concept Analogy Process A house Thread People living in the house Shared memory Rooms and furniture (shared by all) Stack Each person's backpack (private) Process: Running the Chrome browser. Threads: One for the user interface, One for each tab, One for rendering, One for background tasks. Feature Process Thread Memory Has its own memory space Shares memory with other threads Overhead Higher (more OS resources) Lower (lightweight) Communication Requires IPC Can use shared memory Fault Isolation Crash in one doesn’t affect others Crash in one can crash the whole process Creation Time Slower Faster Threads enable concurrency, improving responsiveness and throughput. Processes provide isolation, which is safer for unstable or critical tasks. Choose based on: Speed vs. Safety Available memory/CPU Need to share or isolate data Understanding threads and processes helps you make better choices when designing everything from web servers to distributed systems.  ( 3 min )

Traditionally, Java developers have followed the same standard flow: write Java code, compile it to bytecode, and run it on the Java Virtual Machine (JVM). While this has worked well, it comes with trade-offs: slow startup, high memory usage, and a dependency on the JVM at runtime. Now, thanks to tools like Spring Native and GraalVM, we can compile Spring Boot applications into native executables, binaries that start in milliseconds and consume a fraction of the memory. This lets Spring Boot apps run as fast and light as Quarkus, without having to change to a different framework. In this article, I’ll explain what native compilation means, how it works, and why it makes a big difference for modern applications like microservices and serverless functions.

Let’s first look at Ward Cunningham’s definition of “first-class citizens”: If a programming language places no restrictions on the creation and use of a certain language element, and we can treat this syntactic element the same way we treat values, then we can call this syntactic element a “first-class citizen” in that programming language. Simply put, in Go, functions can be assigned to variables. A function can be passed as a parameter, used as a variable type, or as a return value. In kube-proxy, the function type makeEndpointFunc is defined, with corresponding implementations in ipvs, nftables, and iptables. type makeEndpointFunc func(info *BaseEndpointInfo, svcPortName *ServicePortName) Endpoint Although the implementations are different, by unifying the function type, we can instan…  ( 10 min )

Have you ever wondered how you could isolate your application from external concerns, like which database to use? Or isolating it who is consuming your application? Domain-centric architectures, like the Ports and Adapters, allow you to achieve just that. The Ports and Adapters architecture, also known as Hexagonal architecture, was a concept started by Alistair Cockburn in 1994, but then officially written in his blog in 2005. Its intention is: Allow an application to equally be driven by users, programs, automated test or batch scripts, and to be developed and tested in isolation from its eventual run-time devices and databases. This connected to what we previously stated: isolating the business logic from everything external and that can be ever-changing. Our business logic is the money…  ( 5 min )

In the world of AI, especially with autonomous agents, one core idea gives them their abilities: the agent loop. If you've ever wondered how AI systems stay on track, adapt to changes, and keep moving toward their goals without constant human input, the answer lies in this loop. An agent loop is a cycle that enables an AI agent to keep working toward a goal. Think of it like a feedback loop in a smart assistant or a robot — a continuous process of observing, thinking, and acting. Here’s how the loop generally works: Observe (Gather Data) The agent starts by collecting fresh information. This could be from: Its memory Tools it can access (like APIs or search engines) Sensors (for physical agents) Logs or databases This step is about reading the world as it currently is, not as it was.

It also supports binary backups through disk snapshots. In this blog post, we will describe how to make a backup of FoundationDB via backup_agent. The FoundationDB operator supports making logical backups via backup_agent, but it does not support running DR with dr_agent. We decided to run backup_agent as a separate deployment to allow a symmetric setup with dr_agent. In order to run the backup_agent pods, we will need a deployment. That deployment will need the following: Network level access to the FoundationDB cluster The cluster file to use. This is provided from the c…  ( 8 min )

When working with ASP.NET Core Identity, a set of default tables is automatically created to manage user authentication, roles, claims, and more. These tables are essential for implementing secure and flexible identity management in your application. Here's a breakdown of what each table does: AspNetUsers UserName Email PasswordHash PhoneNumber SecurityStamp, etc. Think of it as the main user profile table. AspNetRoles Each role is stored once and assigned a unique ID and name. AspNetUserRoles many-to-many relationship between users and roles. If one user is both an Admin and a Moderator, this table will contain two entries for that user. AspNetUserLogins external login provider like: Google Facebook Microsoft Twitter, etc. It includes the provider name, key, and associated user ID. AspNetUserTokens 💾 Contains tokens related to a user such as: Password reset tokens Email confirmation tokens Two-factor authentication tokens This helps manage temporary access scenarios securely. AspNetUserClaims For example: SubscriptionLevel = Premium Department = HR These claims are typically used for fine-grained authorization. AspNetRoleClaims 📄 Similar to user claims but tied to roles instead. Example: ✅ ASP.NET Core Identity Default Tables Summary Table Name Purpose AspNetUsers Stores user account info like username, email, password hash, etc. AspNetRoles Stores role definitions (e.g., Admin, User, Manager). AspNetUserRoles Maps users to roles (many-to-many relationship). AspNetUserLogins Stores login data from external providers (e.g., Google, Facebook). AspNetUserTokens Stores tokens for things like password resets, email confirmations, etc. AspNetUserClaims Stores custom claims assigned directly to users. AspNetRoleClaims Stores claims assigned to roles (users get these claims via role membership). If you found this helpful, consider supporting my work at ☕ Buy Me a Coffee.  ( 3 min )

Microsoft recently open-sourced NLWeb, a protocol for adding conversational interfaces to websites.1 It leverages Schema.org structured data that many sites already have and includes built-in support for MCP (Model Context Protocol), enabling both human conversations and agent-to-agent communication. The key idea: NLWeb creates a standard protocol that turns any website into a conversational interface that both humans and AI agents can query naturally. Currently, websites have structured data (Schema.org) but no standard way for AI agents or conversational interfaces to access it. Every implementation is bespoke. Traditional search interfaces struggle with context-aware, multi-turn queries. NLWeb creates a standard protocol for conversational access to web content. Like RSS did for syndica…  ( 7 min )

In the grand, ever-shifting landscape of software architecture, a silent quest perennially unfolds – a search for balance, for that elusive sweet spot where innovation can flourish without collapsing under its own weight. We, as creators of digital worlds, have journeyed from towering, singular strongholds to sprawling, interconnected metropolises. Yet, sometimes, the most profound answers lie not in the extremes, but in a thoughtful fusion of wisdom gleaned from all past endeavors. This is the story of the Modular Monolith, an architectural approach that offers a path to structured grace and sustainable growth. Once, in the nascent days of software development, and even persisting into much of its adolescence, the Monolith reigned supreme. Imagine a vast, ancient citadel, a single, imposi…  ( 8 min )

1. Logical AND (&&) Operator: The logical AND (&&) operator checks whether both operands are true. If both are true, the result is true. If any one or both operands are false, the result is false. // Check if both conditions are true let age = 20; let idProof = true; // Logical AND checks both conditions if (age >= 18 && idProof) { console.log("Allowed"); } else { console.log("Not Allowed"); } Output: Allowed The logical OR (||) operator checks whether at least one of the operands is true. If either operand is true, the result is true. If both operands are false, the result is false. // Check if at least one condition is true let age = 16; let hasGuardian = true; // Logical OR checks if either condition is true if (age >= 18 || hasGuardian) { console.log("Allowed"); } else { console.log("Not Allowed"); } Output: Allowed TheparseInt method parses a value as a string and returns the first integer. It accepts a string argument and optional radix parameter, defining the numeral system base. This method is commonly used for converting string representations of numbers into integers. Example: The method takes two parameters: the string to be parsed and the radix (optional, default is 10). 2 = binary, 8 = octal, 10 = decimal, 16 = hexadecimal. Syntax: parseInt(Value, radix); Parameters: Value: This parameter contains a string that is converted to an integer. radix: This parameter represents the radix or base to be used and it is optional. [Reference - geeksforgeeks] JavaScript provides several ways to execute a block of code repeatedly. These are called looping statements. Executes a block of code as long as a specified condition is true.

Hi. I'm not sure how this works but it said I could make a first post so here goes: How are you all doing? I joined this community (which looks awesome btw) in the hopes of learning more in regards to coding. I have some basic knowledge of coding languages like Python and HTML and have taken part in a hackathon once upon a time. Although I havent made any projects recently and I think thats something I need to work on so I'm going to try my best to do more of that. If you have a project that you're working on and dont mind someone with little to no experience in coding, do let me know. As what I lack in experience I make up for in enthusiasm, words of encouragement and memes. Hopefully if you do let me join your team we get some sort of work done. In all seriousness I plan on getting better at coding so I'll have more to offer. Also if you require a video editor, I am very confident in my video editing capabilities and have made a video for a Star Wars hackathon which I took part in last year (I'll put the video in my next post). Currently I'm self-studying Harvards CS50 intro to computer science and its very interesting. I hope to learn more and grow with you all. Thanks for making this community. P.S I'm a huge Naruto fan (hence my cover image/gif), its a topic I'm extremely knowledgeable about but unfortunately cant add to my CV. Maybe I'll make a Naruto inspired website one day😅  ( 4 min )

Let’s be real: AI is everywhere in language learning right now, but most of it is lipstick on a broken system. Apps love to say “powered by AI” but what does that actually mean? Usually: A glorified chatbot that barely listens Auto-translation features you could get with Google Speech feedback that tells you nothing useful Static lesson plans with no adaptive logic They’re not solving the core problem: getting you confident in real conversations. The AI is passive—reactive at best. It doesn’t push you. It doesn’t correct you in meaningful ways. It doesn’t feel like you're speaking to someone who cares if you get fluent. At YAP, we’re doing it differently: AI conversation partners simulate real humans and nudge you out of your comfort zone. Feedback focuses on communication success, not robotic perfection. Your effort = rewards. Our system pays you in $YAP for showing up and speaking. Rewarding you for your effort and time. Good AI should feel like a partner, not a gimmick. It should make fluency faster, funnier, and a little bit uncomfortable—in the best way. The future of language learning isn’t just AI—it’s AI with incentives. — Team YAP www.goyap.ai  ( 3 min )

In tech, we talk a lot about interfaces. How users interact. How systems are separated by clean abstractions. We build our digital selves like we build UIs. Deliberately curated. Versioned. Deployed. But underneath all that, there is still the raw protocol. The human. The anxious. The tired. The trying. Some borders are not drawn in code. They are inherited in silence. This reflection explores this in a more poetic way. It touches on how identity becomes signal. How ego replaces empathy. How the space between people can start to feel like a firewall. Not political. Just honest. If you have ever felt visible but not seen, or competent but still questioned, this might resonate. It is not about fixing it. It is about noticing when it starts to feel like part of the architecture.  ( 3 min )

GM Folks Ever wanted to build something on the blockchain but felt overwhelmed by all the jargon? Yeah, me too. That’s why I decided to start small, real small with a fun little project: a "Buy Me a Coffee" dApp where people can send me ETH as a tip. (Because, let’s be honest, we all need more coffee and crypto in our lives.) This was my first full-stack Web3 project, and let me tell you. It was a wild ride. From wrestling with TypeScript to debugging weird MetaMask errors, I learned a ton. And now, I’m here to break it all down for you in a way that (hopefully) doesn’t make your brain melt.

Being a developer isn’t just about writing code. Learning new frameworks Building side projects Balancing school, work, or life Trying to stay sane 😅 And if you’re working solo… it hits different. 🧩 “You’re the Developer, the Designer, the PM… and the Janitor.” You come up with an amazing idea. You start building it with full energy. Then life happens: 🎓 You’ve got exams. 📁 Welcome to the “Unfinished Projects” Graveyard That productivity app you started? That AI-powered tool you built 80% of? That portfolio redesign that looked 🔥 but still says “Coming Soon”? They’re sitting in a folder. You swear you’ll finish them “soon.” Every developer has that folder. 💭 So… Why Are We Doing This Alone? What if we: Paired up with others in the same boat? Shared unfinished ideas and built them together? Had spaces where devs could jump in and contribute, no judgment? Imagine an ecosystem where developers hand off projects like relay runners, instead of dropping the baton when life gets hectic. 🧪 Real Talk From Me I was building an AI-powered README Generator. Now it sits there, waiting. And I can’t help but think — if another dev saw the value in it, why not let them take it across the finish line? 🤝 Maybe It’s Time We Collaborate More Sharing half-done projects Asking for help before burnout Building with people, not just for people It doesn’t make you less of a developer — it makes you a smarter one. ✍️ P.S. I might open-source my README Generator soon. If AI + productivity is your jam, ping me. 🧠 What About You? 💬 Drop your thoughts in the comments: What stops you from finishing projects? Is it burnout? Impostor syndrome? Overwhelm? Do you struggle with motivation, feedback, or just too many ideas?

In our previous article, we implemented a client-side image upload functionality using React. Now, it's time to build out the server-side infrastructure to handle these uploads effectively. In this tutorial, we'll create a backend system that not only receives and stores images but also manages their metadata and serves them back to our application. We'll cover setting up file storage, integrating with a database to track image information, and creating endpoints that return essential image data like storage locations. Let's dive into building a complete image management system with Node.js. So, what is the idea? Ok, we will create a separate route that will accept the image, send the file to the storage, and then return some data about that file to the frontend. On the frontend, we will g…  ( 8 min )

In post-exploitation scenarios, few objectives are as valuable as gaining access to the Local Security Authority Subsystem Service (LSASS). Responsible for enforcing security policies and handling authentication on Windows systems, LSASS maintains sensitive data such as passwords, NTLM hashes, Kerberos tickets, cached credentials, and LSA secrets—all in memory. This makes it a goldmine for red teamers and attackers seeking to escalate privileges or move laterally across a compromised network. Understanding how LSASS works, the protections it’s wrapped in, and the techniques to extract data from it using Python gives red teamers not just a powerful tool, but also a clearer view of how defenders might detect or block such attempts. Each time a user logs into a Windows system, LSASS plays a k…  ( 5 min )

Before diving into the web evolution, here's a fun fact: the internet was born from Cold War paranoia! In the 1960s, the U.S. Department of Defense's ARPA created ARPANET — a communication network designed to survive nuclear attacks. The irony? What started as a military defense system became the foundation for cat videos and memes. 💡 Did you know? The first ARPANET message was sent on October 29, 1969, between UCLA and Stanford. It was supposed to say "LOGIN" but crashed after "LO" — technically making the first internet message failed attempt! Timeline: Early 1990s - 2004 Core Traits: Read-only, …  ( 5 min )

O que é DNS O Domain Name System (DNS) é a lista telefônica da Internet. O DNS converte os nomes de domínio (legíveis por humanos, como www.google.com) em endereços IP (que os computadores usam para se comunicar). Cada dispositivo conectado à Internet tem um IP único que as outras máquinas usam para localizar o dispositivo. Os servidores DNS eliminam a necessidade de humanos terem de memorizar endereços IP.

While DEV.to is typically a space for backend architecture and performance optimization, this discussion bridges that world with another deeply technical arena: algorithmic trading. Specifically, we’re talking about latency—the type that separates profitable execution from missed opportunity. Whether you're writing trading bots, building dashboards, consuming exchange APIs, or handling transaction relays, this is a backend performance layer you cannot ignore. In trading, timing is execution. The difference between spotting an arbitrage opportunity and capturing it often comes down to milliseconds. A system can detect a price inefficiency across platforms, but if your transaction arrives a fraction of a second after someone else’s, it’s irrelevant. First arrival wins. Everyone else provides…  ( 4 min )

PostgreSQL limits tuple sizes to a quarter of the block size, generally capping at 2KB. In document data modeling, where documents represent business transactions, sizes often exceed this limit. Storing entire transaction documents as a single JSONB can lead to compression and splitting via TOAST (The Oversized-Attribute Storage Technique). While this is suitable for static documents that are infrequently accessed, it is less optimal for queries on documents.

Managing remote teams isn’t about checking boxes. It’s about enabling people to build, ship, and support software without friction. Developers don’t want fluff. They want tools that work. In 2025, that means choosing tools that cut noise, centralize communication, and sync with code. Remote teams live in different time zones. They use Slack, GitHub, and Google Docs. They code during sprints and debug on-call. When teams don’t share office space, traditional tools fall short. What works in a conference room breaks on Zoom. Developers need: Clear task visibility Fast, async communication Source control integration Lightweight documentation Minimal context switching Tools that miss these points? Dead weight. Teamcamp is a remote, developer-friendly project management platform designed to stre…  ( 5 min )

TL;DR: Tel Aviv University archaeologists Miki Ben-Dor and Ran Barkai argue that early humans (mostly Homo erectus) first harnessed fire not primarily for cooking but to guard huge kills (think elephants, hippos) from predators and to smoke-dry the meat, extending its edible shelf-life. By examining nine prehistoric sites (1.8–0.8 Mya) worldwide—each rich in big-game bones—and ethnographic parallels, they show that the enormous caloric payoff of preserved mega-meat justified the effort of collecting and tending fires. Once fire was routinely available for preservation, roasting foods (evidenced by fish bones ~800 kya) would’ve been a no-brainer “bonus.” This fresh take, published in Frontiers in Nutrition, slots neatly into the duo’s broader theory that early humans’ behaviors largely revolved around hunting large animals and adapting as their sizes—and availability—waned.  ( 3 min )

"ChatGPT is amazing, but how do I integrate this into my own app?" - How many developers have heard this question... LLMs changed our lives, no doubt about it. Since ChatGPT came out, everyone sees incredible possibilities. But let me tell you the truth as a developer: Using this power in our own applications is way harder than we thought. Most of us go through the same cycle. First there's excitement: "I have an amazing AI idea!" Then quick start: We do API integration, simple examples work, everything looks good. But when real users come... that's when everything gets complicated. Code becomes unmanageable, every new feature breaks old code, debugging becomes a nightmare. Did you go through this cycle?

The best translation API you could choose is one that not only is robust with multiple API calls, but also adds value to your app with layers of security for your users. Most cloud translation API's don't provide your app with enough security - and this is needed now more than ever in the age of growing cybersecurity threats. While you can find several cloud translation platforms that run translations through a secure connection (HTTPS), this alone doesn't quite make the cut for user data security in today's world. The best translation API you could choose will do more than use HTTPS protocol. If you read the Terms of Use for a translation API and it makes you think twice, we suggest you consider shopping around for other translation API's.

Hello. So here’s what happened. I recently found out — almost accidentally — that I had summer vacations. Not the planned kind with beaches and iced tea, but the kind that sneaks up on you and leaves you staring at the wall asking, “Now what?” Naturally, I had two options: waste time or waste time in a way that looks productive. I chose the latter. That’s how I stumbled into setting up Neovim. If you don’t know what Neovim is… well, don’t worry, you’re probably happier that way. But if you’re curious (or just here for the chaos), let me walk you through how I went from zero to semi-obsessed with a glorified terminal text editor. So here’s the thing — I recently started learning Go (aka Golang, aka "Google’s gift to minimalists"), and while going through a couple of tutorials, I noticed som…  ( 12 min )

The other day, I was debugging Colorado, a toy project of mine written in C# with Gtk#. Oh, boy, Gtk, the underlying graphic toolkit framework. Most of the times I'm more writing code that I struggle to make it compile than anything else. For instance, I still don't know what an AccelGroup is intended for (apart from the obvious meaning), or what it is used for in order to program keyboard accelerators (like Ctrl+O). Anyway, you have to create one because you need an AccelGroup for your accelerators, no matter what (yeah, I know what the documentation says, but AFAIK, you cannot get the AccelGroup for your app). It's like Gtk has a lot of power, but instead of creating a two-level API (one for the most common case, and another for low-level access), it only has those low-level calls. To ma…  ( 4 min )

Exploring the Intersection of Functional and Object-Oriented Programming in JavaScript The journey of JavaScript has transformed it from a simple scripting language to a robust platform that supports multiple programming paradigms, most notably Functional Programming (FP) and Object-Oriented Programming (OOP). This article aims to provide an exhaustive exploration of how these paradigms intersect in JavaScript, emphasizing the historical context, technical nuances, implementation strategies, performance considerations, and potential pitfalls. JavaScript was born in 1995 through the vision of Brendan Eich. Originally designed as a lightweight programming language for interactivity within web browsers, it showcased an event-driven, object-based programming style. Initially, JavaScript (th…  ( 6 min )

I’m a total dark mode fan. It’s the first thing I switch on whenever I get a new device. Modern browsers finally play nice with dark mode out of the box. So I think it’s time to bring that sleek, eye-friendly aesthetic to the web! Demo | Code A solid dark mode starts with respecting user preferences: :root { color-scheme: light dark; --accent: light-dark(#0d47a1, #ffb300); --canvas: light-dark(#ffffff, #212121); --text: light-dark(#212121, #dcdcdc); } First, we define the color-schemes the page can be rendered in. This ensures that scroll bars, form controls or other user interfaces provided by the browser conform to the specified scheme. In our case, we want the page to support both light and dark modes. Order matters — if the user has no preference, the browser will default to …  ( 6 min )

Decision trees are one of the most intuitive machine learning algorithms - they mirror how humans naturally make decisions. But after diving deep into implementing my own decision tree algorithm, I discovered several critical pitfalls that can completely undermine your model's effectiveness. Here are the key lessons learned that will save you hours of debugging and poor performance. The Mistake: Processing your data in batches and building separate trees for each batch. Why It's Wrong: Decision trees need to evaluate ALL available data at each split to find the optimal decision boundary. When you only use a subset of your data, you're making suboptimal splits based on incomplete information. What to Do Instead: Use your entire dataset for training (memory permitting) If memory is limited, …  ( 5 min )

Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This eighth post introduces you to Perl regular expressions in XS. We should all know what a regular expression is? But if you don’t, here’s a quick refresher: A regular expression (regex) is a sequence of characters that forms a search pattern. They can be used for string matching, searching, and manipulation. Regular expressions are widely used in programming languages, including Perl, to perform complex text processing tasks. In Perl regular expressions can be precompiled and executed using the 'qr//' operator, which allows you to create a regex object that can be reused multiple times. This is particularly useful for performance when the same regex is used re…  ( 8 min )

As a senior software engineer with over a decade of experience, I’ve seen how comments in code can evolve from helpful documentation to misleading traps. Today, I want to share some insights about writing cleaner, self-documenting code. Why Im so down on comments? Because they lie. Not always, not intentionally but too often. The older the comment is the more likely it is to be wrong. The reason is software engineers maintain the code but not the comments. Code will not lie to you but comment will; Code evolves but comments not. Thus comments sometimes will be misleading. Therefore although comments are sometimes necessary, we need to try to minumise them. One of the common motivation for comments is bad code.

The spacebar, once the silent workhorse of the keyboard, is becoming an icon of design, expression, and cultural relevance. The spacebar may seem like just another key, but its role is foundational. It accounts for a significant portion of daily keystrokes—nearly 1 in every 5, according to TypingMetrics' 2023 report. For decades, however, this most-used key remained bland: unmarked, uncolored, and unconsidered in custom builds. But that’s changing. As personalization in tech becomes more prevalent, the spacebar has emerged as a focal point—not just for how it feels or sounds, b…  ( 5 min )

Introduction If we’re going to talk about max width, let’s define it properly first. The max-width CSS property sets the maximum width of an element. It prevents the width of that element (and its content) from exceeding a specific value, even if there's more space available. In today’s digital world, we’re building for a wide range of screen sizes—phones, tablets, laptops, desktops. As web developers, we’re expected to make sites look good and work well across all of them. This is where max-width becomes a crucial part of your responsive layout toolbox. If you’ve ever zoomed in or out in your browser or used developer tools to simulate different screen sizes, you’ve seen how your layout can break when it's not properly handled. It’s easy to unknowingly design just for your own screen, but once you start testing, the need for max-width becomes clear fast. Media queries let you adjust layout styles at different screen widths (often using min-width), but they’re only part of the picture. Max-width ensures your layout doesn’t stretch too far on large screens, helping maintain visual balance and readability.  ( 3 min )

Introduction Git is a powerful version control system that helps developers track changes in their code. Sometimes, you may commit changes accidentally or realize that you need to undo them. That's where git reset comes in. The git reset command allows you to undo commits at different levels: --soft - Keeps changes in the staging area. --mixed (default) - Unstages changes but keeps them in the working directory. --hard - Discards all changes completely. In this guide, we'll explore each option with examples, use cases, and tips to help you undo commits effectively. git reset --soft - Keep Changes Staged This option moves the HEAD pointer to a previous commit but keeps all changes in the staging area(index). git reset --soft HEAD~1 This undoes the last commit but keeps the chang…  ( 7 min )

Purpose In a world where software must evolve or perish, we embrace a principle often overlooked: The value of things that are designed to disappear. Ephemeral Design is a mindset that encourages developers to build systems with impermanence in mind—favoring modularity, replaceability, and minimal long-term baggage. Favor deletion over preservation. Design with a clear exit strategy. Ephemeral Design Manifesto Be honest about what might disappear. Optimize for change, not permanence. Practice Hints Modularize everything: small parts are easier to remove or replace. Isolate experimental features from the core domain logic. Document the lifespan of components, especially if temporary. Avoid over-engineering for uncertain features. Use structure or conventions to indicate ephemerality (e.g., separate directories, metadata, flags)—but balance clarity with elegance. Adopting Ephemeral Design doesn’t mean building carelessly. intentionally, with the courage to discard what no longer serves. Teams that embrace this mindset: Move faster by reducing fear of technical debt Feel safer experimenting and iterating Write more honest, sustainable software Everything is temporary—especially in code. By designing with this in mind, we create systems that are not just flexible, but free.  ( 3 min )

💭 "AWS has 200+ services. How do I remember or use them?" That was me — during my college days, opening the AWS Console for the very first time. It felt like IRCTC with jet engines: options everywhere, nothing made sense.

Article Source: https://juejin.cn/post/7296076144448618506 To further enhance our internal network security, we added the open-source community version of SafeLine WAF on top of our existing hardware WAF as a software WAF at the application layer. This enabled a multi-layered WAF protection architecture. After further exploration, we found that SafeLine WAF's upstream proxy forwarding is based on Tengine. This gave us the idea to use SafeLine not only for WAF protection but also for load balancing and automatic failover. We created a simple HTTP server with a /status route returning HTTP 200. Here's a basic Go example: package main import ( "os" "fmt" "net/http" ) func Hello1Handler(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "I am 11111") } func Hello2Handl…  ( 4 min )

If you've ever translated a document packed with formatting—think footnotes, side-by-side columns, tables, or scanned images—you probably know how quickly it all unravels. Headers vanish. Tables lose their shape. Footnotes crawl into random paragraphs. That’s exactly the kind of mess I ran into. So I started looking for tools that could handle translation and document fidelity—without turning everything into plain text soup. Most tools claim they "support documents" but here's what usually happens: Footnotes get merged with the main body Tables collapse or turn into basic text Fonts and headings lose their hierarchy PDFs with scanned images become unreadable And if your document has two columns, custom fonts, or embedded elements? Most services just aren't built to handle t…  ( 5 min )

In modern software architecture, real-time communication between systems is a necessity. And Webhooks have appeared as a simple and effective method for applications to get updated information from other services instantly. In event-driven systems, it's more important due to the need of responsiveness and automation. A webhook is used to send information from one system to another, in real time, as soon as a particular event happens. Rather than checking with an API at certain times, a webhook allows the source system to send data right away to a predetermined location. For instance, you can use a webhook from Stripe so your application is informed when a payment is successful or unsuccessful. Thanks to this, you can make updates in real time to the order status, send emails or retry logi…  ( 5 min )

GitHub Actions usage reporting doesn't tell the full story. If you're running different types of runners (like 4-core, 8-core, or more), those minutes aren't equal, and your total usage number doesn't reflect it. This guide will show you how to: Export your raw usage data Normalize it by runner type Get an accurate total you can actually budget against \ Why normalizing GitHub Actions minutes matters Runner types in GitHub Actions have different compute capacities and costs. For example, a 4-core runner can do twice the work of a 2-core runner. If you just sum the raw usage, you're underestimating your real consumption and leaving yourself open to surprise bills. Step 1: Export your usage report In GitHub, click your avatar (top right) and go to Settings Select Billing and plans Under Usage this month, click Get usage report Choose your date range (30/60/90 days) and download the CSV You'll now have a CSV showing runner types, quantities, and costs. Step 2: Normalize your minutes Open the CSV in any spreadsheet tool. Focus on the 'sku' and 'quantity' columns. Each runner type has a multiplier based on its compute capacity: Runner Type Multiplier actions_linux 1 actions_linux_4_core 2 actions_linux_8_core 4 actions_linux_16_core 8 actions_linux_32_core 16 To normalize your total usage: For each runner type, multiply the quantity by the multiplier Sum these normalized values across all runner types This gives you the total compute-equivalent minutes your team used during the period. Step 3: Use the data to control costs Without normalized data, you're likely underestimating usage. This normalization process gives you a real number to track, budget against, and compare over time. Take it further with Depot Once you know how many minutes you're actually burning, the next step is cutting them down.

Introduction When I began my ROS2 integration project, AppArmor wasn't even on my radar. My background included years of experience with RHEL and Oracle Linux, and I had developed a solid understanding of SELinux. Initially, I attempted to make ROS2 work on Oracle Linux, expecting a straightforward integration. However, after several days of troubleshooting and configuration tweaks, I was still encountering persistent issues. Next, I shifted my focus to using SELinux on Ubuntu. Unfortunately, this too presented complications that weren't worth resolving at the time. Although both SELinux and Oracle Linux theoretically support ROS2, the practical reality was too time-consuming to justify. On the other hand, I knew that AppArmor was the default MAC (Mandatory Access Control) system on Ubun…  ( 5 min )

Here’s where KMSPico…  ( 5 min )

In this way, a progress bar with dots is compl…  ( 3 min )
